According to the Press and Journal, new comments from Scottish police throw light on the challenges facing their investigation into 'torture flights'. 

The police are investigating claims that CIA planes used Aberdeen, Inverness and Wick airports during 'war on terror' operations.  Lord Advocate James Wolffe suggested that the "complex and challenging" police investigation could not conclude until evidence was "obtained" from overseas. 

In 2014, the United States Senate Intelligence Committee published a redacted executive summary to its 5000 plus page report on the CIA's detention and interrogation programme. 

Scottish police confirmed to the Press and Journal yesterday that they are still waiting to receive a full copy of the report, despite requesting it in December 2014.
