LONDON - Libya's transitional justice minister says the case is closed on the 1988 Lockerbie airplane bombing.

Mohammed al-Alagi noted that the only man convicted in the case, Abdel Baset al-Megrahi, was freed on compassionate grounds because of illness and said there's no reason to keep dragging the case into court.

His remarks to reporters in Tripoli on Monday come after Scotland said it has asked Libya's new authorities for help to catch those responsible for the bombing, Britain's worst terrorist attack.

The Scottish prosecutors' office said it has asked the National Transitional Council, which has been governing the country since Moammar Gadhafi's fall, for written evidence and witnesses that could aid the inquiry.

Asked for his response, al-Alagi said "the case is closed."
