Officers from Dumfries and Galloway Police have visited Libya as part of their investigation into the Lockerbie bombing.
They met senior officials from the Libyan Government in Tripoli on Monday. Abdelbaset al-Megrahi, who died last year, is the only person to have been convicted of the atrocity.
Investigators are trying to find out if there are others in Libya who could be brought to trial.
Scotland's Lord Advocate has described the discussions as "positive".
"As announced by the Prime Minister on 31 January, visas were granted for Scottish police and prosecutors to travel to Tripoli to meet with their counterparts in progressing the investigation into the Lockerbie bombing.
"Senior officials from Crown Office, Dumfries and Galloway Police and the FBI attended a series of meetings in Tripoli with ministers and senior officials from the Libyan government to discuss the ongoing investigation.
"The purpose of the meetings was to discuss US and Scottish requests for co-operation in the ongoing investigation and to agree how these would be progressed.
– Scotland`s Lord Advocate, Frank Mulholland QC.
"The discussions were positive and it is hoped there will be further progress as a result.
"The Libyan authorities did raise the issue of compensation, as today's press reports have indicated, and it was reiterated by the joint delegation that the investigation was focussed on identifying others involved in this act of state sponsored terrorism.
"As the investigation remains live, and in order to preserve the integrity of that investigation, it would not be appropriate to offer further comment."
