were later found to have been switched on on 6 December. Scottish police had also failed to inform the defence that another witness had testified seeing Libyan men making a similar purchase on a different day. An official report, providing information not made available to the defence during the original trial, stated that on 19 April 1999, four days before identifying al-Megrahi for the first time, Gauci had seen a picture of al-Megrahi in a magazine that connected him to the bombing, a fact that could have distorted his judgement. Gauci was shown the same magazine during his testimony at al-Megrahi's trial and asked if he had identified the photograph in April 1999 as being the person who purchased the clothing; he was then asked if that person was in the court. Gauci then identified al-Megrahi for the court, stating, "He is the man on this side. He resembles him a lot". A circuit board fragment, allegedly found embedded in a piece of charred material, was identified as part of an electronic timer similar to one found on a Libyan intelligence agent who had been arrested 10 months previously for carrying materials for a Semtex bomb. The timer was allegedly traced through its Swiss manufacturer, Mebo, to the Libyan military, and Mebo employee Ulrich Lumpert identified the fragment at al-Megrahi's trial. Mebo's owner, Edwin Bollier, testified at the trial that the Scottish police had originally shown him a fragment of a brown eight-ply circuit board from a prototype timer which had never been supplied to Libya. Yet the sample he was asked to identify at the trial was a green 9-ply circuit board that Mebo had indeed supplied to Libya. Bollier wanted to pursue this discrepancy, but was told by trial judge Lord Sutherland that he could not do so. Bollier claimed that in 1991 he had declined an offer of $4 million from the FBI (equivalent to $ million in dollars) in exchange for his support of the main line of inquiry, though this claim has never been verified. Criminal inquiry Known as the Lockerbie bombing and the Lockerbie air disaster in the UK, it was described by Scotland's Lord Advocate as the UK's largest criminal inquiry led by the smallest police force in Britain, Dumfries and Galloway Constabulary. After a three-year joint investigation by Dumfries and Galloway Constabulary and the US FBI, during which 15,000 witness statements were
