Lockerbie bombing: Former FBI chief expects more arrests

17 December 2013 Last updated at 15:03 GMT

Robert Mueller, a former director of the FBI, has told BBC Scotland that he expects more people will be charged over the Lockerbie bombing.

The case remains open 25 years after Pan AM flight 103 exploded over southern Scotland on 21 December 1988, killing 270 people.

Investigators have said the Libyan revolution has opened up new lines of enquiry but some Lockerbie campaigners doubt the case will ever be fully resolved.

BBC Scotland correspondent Glenn Campbell reports from the US.
