too, in Malta, just a few weeks previously. At this point, the Scottish police believed they might be in a position to make an arrest. However, days later the Sunday Times of London became aware of the story, not least because of the Scottish detectives' habit of going for a walk together at lunchtime every day, conspicuous as a group in their black police officers' trousers and white shirts. Rumours spread around the island that the Lockerbie police were in Malta looking for the bomber. An American journalist who approached one of the detectives to ask whether he was from Lockerbie was told "No comment" in a broad Scottish accent, which was taken as confirmation, and the story reached David Leppard, then an investigative reporter with the Insight team of the Sunday Times, who published the story. Any chance of arresting the suspect in Malta was lost. Before the detectives left his store that day, Gauci remembered something else.

This match confirmed to the Scots that the man Gauci had sold the clothes to was, indeed, the man they were looking for. Doubt has since been cast on the reliability of Gauci as a witness; five years after the trial, former Lord Advocate, Lord Fraser of Carmyllie, publicly described Gauci as being "an apple short of a picnic" and "not quite the full shilling", and it was revealed in 2007 by the Scottish Criminal Cases Review Commission that Gauci was interviewed 17 times by Scottish and Maltese police during which he made a series of inconclusive statements. In addition, a legal source said that there was evidence that leading questions had been put to Gauci. In the BBC Two The Conspiracy Files: Lockerbie shown on August 31, 2008, it was claimed that one significant reason for Megrahi's latest appeal was that
