Mohammed was subjected to harsh interrogations in Poland. Agency officers and contractors forced him to stay awake for 180 hours, according to a CIA inspector general’s report. He also underwent 183 instances of waterboarding, or simulated drowning.
After the CIA prison in Poland was closed in September 2003, Mohammed was moved to Bucharest, to a black site code-named “Britelite.” Soon the CIA was trying to find ways to entertain Mohammed as his intelligence value diminished.
The prison had a debriefing room, where Mohammed, who saw himself as something of a professor, held “office hours,” as he told CIA officers. While chained to the floor, Mohammed would lecture the CIA officers on his path to jihad, his childhood and family. Tea and cookies were served.
Along with the other five detainees at the prison in Bucharest, Mohammed was given assignments about his knowledge of al-Qaida, or “homework,” as CIA officers called it. He was given Snickers candy bars as rewards for his studiousness.
Though Mohammed enjoyed the Harry Potter books, they were a source of frustration for the CIA officers at the prison. For security reasons, after a prisoner finished a book, they tediously checked every page to ensure detainees weren’t passing messages.
