FBI officials visiting an overseas prison run by the CIA found prisoners 'manacled to the ceiling and subjected to blaring music around the clock', according to the documents.

Handwritten notes attributed to Justice Department officials discuss the possibility of prosecuting CIA employees. Senior FBI officials questioned the legality and effectiveness of the CIA's interrogation methods and prison conditions. An interrogation involving threats with a gun and power drill was the focus of discussion in the notes, but Justice Department officials eventually declined to prosecute the CIA official.
