New evidence has emerged that could throw doubt on the conviction of the man found guilty for his part in the Lockerbie bomb blast.
A Heathrow Airport security guard said Pan Am's baggage area was broken into 17 hours before Flight 103 took off for New York.
A report in the Mirrornewspaper says Mr Ray Manly reported the break-in at the time and was interviewed by anti-terrorist officers the following month.
But his evidence was lost, the newspaper said, and formed no part of the trial in a Scottish court sitting in Camp Zeist, Holland.
Libyan Mr Abdelbaset Al Megrahi was jailed for a minimum of 20 years in January. Fellow Libyan Mr Al Amin Khalifa Fhimah was acquitted.
As Flight 103 passed over Lockerbie in December 1988 it was ripped apart by a bomb, killing all 259 passengers and crew, as well as 11 Lockerbie residents.
During the trial, prosecutors claimed that Al Megrahi placed the bomb on a flight from Malta to Frankfurt, where it was then "interlined" on to a flight to Heathrow before being loaded on to Flight 103.
But the defence said it was more likely the bomb was introduced at Heathrow.
