Investigators believe the luggage container in which the bomb that destroyed Pan Am Flight 103 was hidden was put on the jumbo jet in Frankfurt, West Germany, a newspaper reported Wednesday.

Police said Tuesday they had identified the luggage container, but would not comment on whether it was placed on the flight in Frankfurt or London."We have now identified the baggage container within the aircraft in which the explosive device was placed, and substantial forensic and reconstructive work is being undertaken in this regard," said Detective Chief Superintendent John Orr, the Scottish police officer heading the investigation.

"No details of the container, what else it held, where it was discovered or where it originated were given officially but police and accident investigators are now convinced that it was in luggage first loaded at Frankfurt," the Times of London said Wednesday.

Police and Department of Transport spokesmen refused Wednesday to elaborate on Orr's remarks or comment on The Times' report.
