[What follows is excerpted from a long article just published in English on the website of Neue Zürcher Zeitung. The original German language version was published on 14 June:]
Thirty-six years after the bombing of Pan Am Flight 103 over the Scottish village of Lockerbie, US prosecutors are pursuing a new case stemming from the terrorist attack. At the center of the investigation is a colorful entrepreneur from Zurich and his claims of conspiracy.
Edwin Bollier, now nearly 88 years old, sits in his office on Badenerstrasse in Zurich and says: "The book is written. All I have to do is pull it out of the drawer." In his book, Bollier finally wants to tell what he sees as the whole truth about the 1988 Lockerbie bombing, in which more people were killed than in any terrorist attack in Europe since. (...)
Now, at last, US prosecutors are bringing their own case relating to what President Ronald Reagan called the "attack on America." Many years ago, a mid-level intelligence agent from Libya was convicted in Scotland of being involved in the attack. However, some observers never gave up their doubts about this guilty verdict. A figure accused of being an accomplice of the convicted man is currently in custody in the United States, and a new round of legal procedures is underway.
US prosecutors in Zurich
Last year, two prosecutors and a judge traveled to Zurich to question Bollier as a witness. He is confident that the American court will follow his lead when it ultimately makes its ruling. "I have provided all the information necessary to finally expose the conspiracy," he says.
Bollier argues that it was not in fact Libyan leader Muammar Gaddafi's intelligence service that was behind the bombing, but rather a Syrian-Palestinian commando group acting on behalf of Iran.
Bollier says he is waiting for the US court verdict to be issued before publishing his book. However, the court handling the case recently postponed the trial date originally set for May, citing, among other factors, the "complexity" of the case.
Bollier isn’t concerned. He says he is prepared to testify whenever the trial takes place.
No one knows PT/35 (b) as well
The Zurich entrepreneur is also one of the key figures in the US court proceedings. No one is as familiar with the piece of evidence with the file number PT/35 (b) as well as he is. This exhibit is no larger than a fingernail. It is only 1 millimeter thick, and weighs less than 1 gram.
For more than 30 years, the entire Lockerbie case has hinged on this tiny piece of evidence.
It comes from an electronic circuit board, the kind of technology found in every smartphone today. A circuit board is flat, made partially out of conductive metal, and serves as the foundation on which the components necessary for an electronic device are built. The circuit board to which the fragment in question belonged before being torn out by the explosion in the Boeing 747 was part of a timer-based detonator.
Out of the huge, several-ton pile of debris that was recovered in Lockerbie, PT/35 (b) is the only piece that points to Libya. Without this tiny fragment, the Libyan intelligence agent named Abdelbaset Ali al-Megrahi could not have been charged.
In his office on Badenerstrasse, Bollier is poring over files. He reads them without glasses, even the small print. When he talks about Lockerbie, which he usually does almost without pause for breath, he sometimes mixes up names or dates. Then his wife Mahnaz, a native Persian who came to Switzerland after the fall of the shah, comes to his aid.
It didn't take her long to became part of Team Bollier, and today she knows the Lockerbie case's ins and outs almost as well as her husband.
The film and TV industry has also been subjecting the crash of Pan Am 103 to a thorough reexamination. Several productions have called the Scottish court ruling into question, in some cases openly postulating a miscarriage of justice. The streaming platform Sky is showing an ambitious documentary on the subject, paired with a successful dramatization of the incident as a series starring Colin Firth in the lead role. Its rival Netflix will soon follow with a program produced in collaboration with the BBC.
Too sensitive for Al Jazeera
However, the most controversial production has proved to be a multipart series created by Arab television network Al Jazeera. One episode was withdrawn after broadcast, and the last episode was not broadcast at all. Apparently, it was too controversial for the network’s Qatari owners. The NZZ has viewed all episodes of this series. It reveals previously unknown information that adds weight to suspicions that Iran was behind the attack.
Sooner or later, every documentary filmmaker addressing this subject finds their way to Badenerstrasse 414 in Zurich – that is, to Bollier's office. The BBC has sent its film crews here, as have Sky and Al Jazeera. The multistory concrete building in Zurich's Nova Park gives the feeling of having been drawn from another era. Stepping into the third-floor office with the sign "MEBO LTD," a visitor might well feel that they had been transported back to the 1970s. (...)
Explosives in a cassette recorder
On the evening of Dec 21, 1988, Pan Am Flight 103, bound from London to New York, had just reached its cruising altitude of 9,000 meters when a bomb exploded in the cargo hold. A timer-based detonator built into a Toshiba cassette recorder had triggered the explosion. The plane crashed.
All 259 passengers and crew members, most of them US citizens on their way to their Christmas holidays, were killed. An additional 11 people at the crash site in Lockerbie also lost their lives.
The delivery to Libya
A few years previously, in 1985, Bollier's small electronics company Mebo had delivered 20 timer devices to Libya – of the same model that triggered the explosion. This delivery is a matter of record and is undisputed.
The name "Mebo" is drawn from the names of the two company founders, Erwin Meister and Edwin Bollier. While Meister has long since withdrawn from public life, Bollier is still fighting on the front lines to defend his company's reputation.
Mebo Ltd. was a simple trading company with a focus on electrical appliances. It even developed a few devices itself. This included a timer with the model number MST-13. An engineer, Mebo’s sole employee, had developed the device in a small workshop. A third-party company manufactured the MST-13 timer according to his plans.
The Libyan army was almost the sole purchaser of these timers. A few additional units were sold to the Stasi, East Germany's secret police agency.
"But we didn't supply detonators to Libya. Just electronic timers," Bollier insists in an interview in his office.
This distinction is important to him – after all, a timer is not in itself a weapon. A timer becomes a weapon only if it is connected to a detonator. Mebo did not do that, Bollier says. Libya thus must have hooked up the detonator itself.
The business owner picks up a timer that is sitting on his desk in his office. The MST-13 is about the size of a fist. It is nothing more than a simple timer, he says. "Similar to an alarm clock or an egg timer, only a bit more robust, fireproof and waterproof."
Mebo had an export license for the delivery of the timer-based switches to Libya and the East German government. The Swiss agency in charge of overseeing such exports did not find that this contract violated the country’s Federal Act on War Materiel.
Because the issue is so important to him, we have agreed with Bollier to use the English word "timer" throughout this article, even in its German-language original – referring both to timers with and without detonators attached.
And what did the Libyan army use the timers from Switzerland for? Bollier insists that the army used them as defensive weapons. The sale came during the desert war against neighboring Chad. The timers were set in military camps where capture was deemed a possibility, he says. If a squad was able to retain its position, it would defuse the explosive. However, if a camp were to be captured by the enemy, the device would go off at some point.
Bollier has never been charged with any crime in connection with the Lockerbie bombing, either as an accomplice or an accessory, even though the Scottish authorities did consider doing so. In Switzerland, the Office of the Attorney General initiated criminal proceedings, but these were discontinued after four years.
Bollier has always appeared in court only as a witness. For more than 30 years, he has been saying the same thing: that the Lockerbie discovery, exhibit PT/35 (b), that tiny fragment of bomb-wrecked timer, differs in various details from the timers that Bollier’s firm delivered to Libya.
For example, he argues that the fragment exhibits characteristics that were introduced only in 1990, more than a year after the crash of Pan Am Flight 103.
Only one conclusion can be drawn from this, says Bollier: "Someone must have placed the find at the crash site after the fact, in order to lay a false trail pointing to Libya."
Brown instead of charred
When investigators from Scotland and the US first showed him a photo of the discovery, Bollier recognized it immediately. That was in 1990. "In the photo, the fragment was brown," he recalls. "But after the explosion, it should have been charred."
When he later saw the original of the PT/35 (b) fragment, it was no longer brown – it was charred, he says. From this, Bollier concludes that the alleged find is not only a forgery, but was also tampered with after the fact.
This is clearly an outrageous accusation. But Bollier stands by it. He refers to the alleged forgers and manipulators of the only piece of conclusive evidence from Lockerbie as "Group XXX." By this he means those within Scottish and American government agencies that he says were responsible for this falsification, in cooperation with the Swiss intelligence service, which was then a part of the Federal Office of Police.
However, as someone making such a serious accusation, Bollier has a problem: His credibility is in tatters.
Someone once said that Bollier was the worst witness imaginable, thanks to his dubious past. Anyone who did business during the Cold War with the secret police and intelligence services of Libya and East Germany, with Gaddafi’s «Jamahiriya» state and the Stasi, has inevitably seen their reputation permanently damaged.
Bollier's fight for the truth, as he calls it, is therefore also a fight for his own rehabilitation. Furthermore, if the trail to Libya does indeed turn out to be falsified and manipulated, this would do more than exonerate Bollier morally – he would also be entitled to the equivalent of millions of dollars in financial compensation.
However, Edwin Bollier is not alone in his assertion that exhibit PT/35 (b) was planted at the Lockerbie crash site after the fact. Jim Swire is convinced of this as well.
Bollier’s opposite
When it comes to credibility, Swire is the opposite of Bollier. The English doctor lost his 23-year-old daughter Flora in the bombing of Pan Am Flight 103. With his clear independence and unimpugned integrity, he soon became a respected spokesman for the families of the British victims.
Bollier and Swire share the same view. But it is no coincidence that Colin Firth is playing the English country doctor rather than the Swiss wheeler-dealer in Sky’s dramatization of the events.
Since the crash of Pan Am 103, Swire has dedicated his life to finding his daughter’s murderers, as he consistently refers to them. At 89 years old, he still hasn't achieved his goal.
Swire once campaigned vigorously to bring Libyan defendant Abdelbaset Ali al-Megrahi and his alleged accomplices to trial in Scotland. When, after much back and forth, that trial finally took place on neutral ground at the former Camp Zeist military base in the Netherlands, Swire did not miss a single one of the 85 days of proceedings.
Nothing would have made him happier than to know at last who had been responsible for his daughter's death. But at the end of the trial, he found himself convinced that al-Megrahi was innocent, and had nothing to do with the bombing.
Befriended the convicted attacker
On the day the verdict was announced, Swire was so distraught that he suffered a breakdown. He was shocked by al-Megrahi's conviction – along with the simultaneous acquittal of his alleged accomplice – and disappointed by the Scottish justice system.
Swire visited al-Megrahi several times in prison, and ultimately became friends with him. When the Libyan was diagnosed with cancer, Swire spoke out strongly in favor of his release. «The sooner he is released, the better,» he was quoted as saying in the NZZ am Sonntag newspaper.
When al-Megrahi was dying in 2012, Swire traveled to Tripoli amid the unrest following Gaddafi’s fall. Even on his deathbed, al-Megrahi protested his innocence.
Swire fulfilled his last wish. In his book published in 2021, the key message is that fragment PT/35 (b) cannot have come from any of the 20 timers that Bollier's Mebo had once delivered to Libya – and that al-Megrahi's conviction was therefore a miscarriage of justice.
The FBI on board
The investigation into the bombing was led by the Scottish police. However, the United States' domestic intelligence service, the FBI, was also involved from the beginning – a concession made to the US by the Scottish authorities in view of the large number of victims from America.
The unusual collaboration made the enormous investigation – featuring a debris field alone that stretched over several dozen square kilometers – even more complicated. «We weren't used to not being in the lead,» says the self-assured FBI Special Agent Richard Marquise in one of the many documentaries about Lockerbie.
However, by tapping its global network, the FBI was able to open up various sources that would have remained closed to the Scottish police. "Even the CIA supported us," Marquise once said. Given the rivalry between the two major US intelligence services, this was unusual, he noted.
Yet despite years of investigation and a huge pile of files, the case ultimately led only to the disputed conviction of the single Libyan intelligence agent.
The trail to Iran
Initially, everything pointed in a different direction. Indeed, after just a few months, the Lockerbie case seemed to have been solved, with investigators regarding it as a probable act of retaliation by Iran.
On July 3, 1988, a few months before Lockerbie, a US Navy warship shot down an Iranian passenger plane in the Persian Gulf – accidentally, according to official statements. All 290 passengers, including 66 children, were killed.
Iran's revolutionary leader Ayatollah Ruhollah Khomeini publicly vowed revenge, saying that an American aircraft carrying many passengers would be shot down. There was subsequently much to suggest that the Iranian regime had commissioned a commando group from Syria known as the Popular Front for the Liberation of Palestine-General Command, or PFLP-GC, to carry out the retaliatory action.
The PFLP-GC operated from Syria under the command of Ahmed Jibril. In 1970, his agents had used a parcel bomb to bring down Swissair Flight 330 over Würenlingen, killing all 47 passengers. In that instance, the explosive was built into a radio and triggered by an altimeter.
Thanks to the investigations in the Würenlingen case, hardly anyone in the West was as familiar with the PFLP-GC as the Swiss Office of the Attorney General. Six months after Lockerbie, in late May 1989, three Scottish investigators thus traveled to Bern to exchange information with their Swiss colleagues.
The secret meeting lasted two days, turning up striking parallels. The plastic explosive used in the Lockerbie bombing had been Semtex, which was manufactured in Czechoslovakia. This was the same material that had been used in Würenlingen. Even the bomb maker appeared to be the same individual, a Jordanian named Marwan Khreesat.
A few weeks before Lockerbie, in late October 1988, Khreesat had been arrested in Düsseldorf as part of a broad operation dubbed "Autumn Leaves." In total, German police arrested more than a dozen members of the PFLP-GC – dealing a serious blow to the terrorist group.
During the raid, police also seized four electronic devices, all of which had been rigged with explosives. One of these devices was a Toshiba portable radio.
It thus appeared that German police had foiled a planned series of attacks by the PFLP-GC. However, interviews with the detainees revealed that the terrorists had originally prepared five such devices, not just four.
The conclusion seemed obvious: The fifth electrical device must have been the Toshiba cassette recorder that exploded on Pan Am Flight 103 over Lockerbie.
When the Scottish delegation bid farewell to their Swiss colleagues on May 25, 1989, the case appeared to be solved. Investigators believed that the Toshiba cassette recorder containing the explosives had been loaded into the cargo hold of a Boeing 747 at Frankfurt Airport on the Pan Am 103 A feeder flight to London Heathrow.
This conclusion was stated in the minutes drawn up by the Swiss Office of the Attorney General following the meeting with their colleagues from Scotland. After a lengthy tug-of-war, the Switzerland-based Beobachter magazine published these minutes a few years ago.
But then everything changed.
The shift to Libya
No arrest warrant was issued for Khreesat, the alleged bomb maker, or for any other member of the PFLP-GC initially suspected of involvement.
Instead, the Scottish police and the FBI, who had been focusing their part of the investigation on Iran, issued arrest warrants for two previously unknown Libyans: Abdelbaset Ali al-Megrahi and an alleged accomplice, the station manager of the Libyan Arab Airlines in Malta.
Exactly how these arrest warrants came to be issued remains unclear today. Apparently, they were based on secret information from the CIA and a somewhat shady agent in Malta.
In his office, Bollier rummages through one of the many piles that have accumulated in an adjoining room over the past decades.
He finds the newspaper article he is looking for, and offers a summary: The surprising turnaround in the investigation was the result of the geostrategic climate at the time, which was very different from today's. The United States and the United Kingdom, which at the time were at war with Iraq, did not want to spoil their relationship with Iran’s government as well.
Thus, the article argued, shifting blame for the Lockerbie bombing to Libyan leader Gaddafi and his intelligence agents proved a convenient alternative. After all, their April 1986 attack on a West Berlin discotheque frequented primarily by American soldiers had gone unpunished.
«It's that simple,» Bollier says, tossing the newspaper article back onto the pile.
It is possible that for the U.S. and the U.K., Libya was seen as a more convenient scapegoat than Iran at that point in history. However, like so much else in the Lockerbie case, this theory cannot be proven.
Gaddafi's photo on the side table
This difficulty doesn't impress Bollier. In his office on Badenerstrasse, the presence of long-deposed Libyan despot Gaddafi can still be felt everywhere. A framed photo of the young Gaddafi is placed on the side table next to the sofa, leaning against an iron palm tree.
During Gaddafi's more than 40 years in power, his regime systematically violated human rights. It engaged in countless arbitrary arrests, imprisoning and torturing opposition figures. Many of these individuals disappeared or were executed.
Bollier offers a kind of counterpoint, however. "Gaddafi may have blood on his hands," he says. But from the leader’s own point of view, he had been acting in the interests of the Libyan people, Bollier says. The entrepreneur counts off the gains: roads, housing, infrastructure – "everything in tiptop shape," he says.
It is jarring statements like this that undermine the image of Bollier as a fearless fighter for the truth.
An office for the alleged attacker
Another startling fact reveals just how close Bollier's relationship with Gaddafi's internationally ostracized regime was: Mebo temporarily rented an office at Badenerstrasse 414 to two employees of the Libyan intelligence services – one of whom was Abdelbaset Ali al-Megrahi.
Bollier plays this down. It was purely business, he says. And anyway, al-Megrahi visited Zurich only two or three times a year.
Bollier started doing business with Libya in the mid-1970s. Even before media pioneer Roger Schawinski shook up Switzerland's media landscape by founding his Radio 24 station – which broadcast as a pirate station from Pizzo Groppera in Italy before eventually becoming the country's first commercial radio station – the trained radio engineer Bollier had been operating his own pirate radio station in the North Sea. He had chugged around the international zone in a converted ship, competing in turn with the state broadcasters in England and the Netherlands.
"It was a lucrative business for a while," recalls Bollier – until the authorities shut the pirate station down.
$4.9 million from Gaddafi
That left Bollier sitting on an expensive ship crammed full of electronics that nobody wanted. Only one person showed any interest: Muammar Gaddafi. The Libyan ruler paid Bollier $4.9 million for the former pirate radio craft.
Nor did this prove to be the only such deal. Although Bollier says he never met Gaddafi in person, the Libyan state became the Swiss entrepreneur’s most important customer. Contracts with the military and intelligence services soon followed. In the 1980s, Bollier installed Tripoli’s first fax machines, after purchasing them first from a distributor in Zurich. "For this, the Libyans, who had never seen a fax machine before, celebrated me like a hero," he says.
The fax machines were soon followed by the delivery of the MST-13 timers to Libya.
The circumstances surrounding the discovery of the fingernail-sized fragment PT/35 (b), which is supposed to have come from one of these timers from Zurich, are striking. Scottish police found it six months after the crash, in late May 1989, in a wooded area more than 30 kilometers from the crash site. The fragment was stuck inside the collar of a Salomon-brand shirt that had originally been purchased in Malta.
That shirt had wound up in a maroon Samsonite suitcase along with the Toshiba cassette recorder that was rigged with explosives.
No pieces belonging to the timer's significantly larger and more robust housing were ever found. In some official documents, the date of discovery is given not as May 1989, but rather as January 1990 – that is, more than a year after the crash. These dates are important for Bollier's argument.
The Scottish police initially had no idea what to make of their chance discovery. They searched unsuccessfully at 54 companies across 17 countries in hopes of tracking down the origin of the PT/35 (b) fragment.
Help from the FBI and CIA
In early 1990, the Scottish police asked their colleagues at the FBI for help. These investigators then quickly found what they were looking for: The fragment was an exact match with a timer-based detonator that the CIA had seized during a raid in Togo in 1985, they said. Through some convoluted means, a Mebo MST-13 timer had apparently found its way to the rebels in Togo.
However, over the years, investigative journalists have uncovered inconsistencies in this conclusion. One such reporter is Otto Hostettler from the Switzerland-based Beobachter magazine. He has published several articles on the discrepancies in the Lockerbie case.
Like Bollier, Hostettler also concludes: "The item labeled PT/35 (b) cannot have come from the shipment to Libya that Edwin Bollier made in 1985." The fragment contains technical components that had not even been developed at that time, the reporter notes.
Moreover, in addition to Jim Swire, the representative of the victims' families, and investigative journalist Hostettler, there are still other unimpeachable figures who agree with Bollier that something is not right about PT/35 (b).
The odd role of Switzerland's intelligence service
The role played by one senior member of the Swiss Federal Office of Police, which was Switzerland's intelligence service at the time, is nothing less than striking. It is a matter of record that on June 22, 1989, six months after Lockerbie, this intelligence service agent appeared at the Badenerstrasse 414 building. On the third floor, rather than visiting the Mebo Ltd offices, he instead ended up in the workshop on the other side of the corridor. There he met with the engineer who had developed the MST-13 timer.
This is publicly known because Bollier later reported the intelligence service agent to the authorities. The entrepreneur accused this figure of stealing a timer from Mebo's inventory and passing it on to the FBI, all without a search warrant. Bollier demanded 6 million Swiss francs in damages from the intelligence service agent.
As part of the criminal proceedings, the Swiss Office of the Attorney General summarized the facts of the case in a written statement. That statement is dated July 30, 2012, and is signed by the head of the office's National Security division
According to this statement, the employee of the Federal Office of Police did indeed receive a timer from the Mebo engineer, "which he passed on to the American authorities."
"The evidence is said to have been subsequently tampered with," says the Office of the Attorney General’s written statement. Followed by: "This assertion by Bollier has not simply been pulled out of thin air."
The Attorney General’s Office explains why Bollier’s assertion could be correct as follows: "In any case, an expert opinion provided by the scientific service of the Canton of Zurich proves that the timer handed over to the Swiss federal police and the timer fragment presented as evidence by the Scottish authorities cannot be identical."
No other authority has adopted Bollier’s thesis that exhibit PT/35 (b) was falsified as clearly as the Swiss Office of the Attorney General, in this written statement.
However, the Zurich cantonal police report referred to in the Attorney General’s statement has never subsequently turned up. This is confirmed by respected Zurich lawyer Marcel Bosonnet, who represented Bollier in this case.
The Swiss Federal Supreme Court never addressed the claim for damages – Bollier had submitted it too late.
"In my opinion, there was a lack of will to get at the truth," Bosonnet says. In so doing, Switzerland missed a unique opportunity to resolve the Lockerbie case, he adds.
Al Jazeera reports on secret meetings
This clue prompted the researchers at Al Jazeera's English-language service to work even harder. Their documentary series, which has since been withdrawn, describes how, over the course of 1988, a few months before the Lockerbie crash, several meetings took place involving representatives of the intelligence services of Iran, Syria and Libya, as well as of Hezbollah and the PFLP-GC. The common goal was reportedly a militant campaign financed by Iran against targets in the US and Israel, which was to include shooting down passenger aircraft.
According to Al Jazeera's reporting, these secret meetings took place between March and October 1988 in Malta, Cyprus and Lebanon.
In the documentary, Robert Baer is given considerable time to speak. This author, a former CIA agent, has long argued that Iran, not Libya, was behind the Lockerbie attack. He has been joined by other voices from within American intelligence circles.
Baer told Al Jazeera that he had evidence showing that a few days after the attack on Pan Am 103, in late 1988, $11 million had been transferred from Iran to a bank account in Lausanne. Some of this money was later transferred to the accounts of two leading members of the PFLP-GC, he contends.
Baer is no longer employed by the CIA. Nevertheless, he is bound by the principle that anything he makes public based on knowledge gained during his time in service must be approved in advance by the CIA.
In Al Jazeera’s withdrawn documentary series, he says that he had followed this process in order to divulge his information. He additionally says that there is consensus within CIA and FBI circles that Iran was responsible for the Lockerbie crash.
So has Gaddafi's Libya been wrongly blamed, for more than 30 years, for one of Europe's most devastating terrorist attacks?
Despite the numerous proponents of this theory, the question is still not easy to answer. In fact, a new book published in early 2025 argues against this conclusion.
"Top secret" handwritten letters
In this book, the authors present previously unpublished archive material from the Gaddafi-era Libyan intelligence service. Handwritten letters marked "top secret" describe how, in October 1988, a division of the intelligence service in Tripoli carried out experiments with explosives, including detonating a suitcase.
At the time, the head of this division was Abdelbaset Ali al-Megrahi, the Libyan intelligence agent who had protested his innocence on his deathbed.
Prosecutors in the US are aware of this archive discovery. The postponement of the ongoing trial is likely to be related to efforts to verify documents that were not previously part of the record.
Meanwhile, back in Zurich, Edwin Bollier is keeping his book in his drawer, ready to publish. Mr Lockerbie, as he calls himself in his email address, is at least willing to reveal his title: "The Truth Died at Lockerbie."
