Gul Rahman was naked from the waist down and chained to the concrete floor of a makeshift prison when he was found frozen to death.
Wearing only a sweatshirt, he had been held inside a facility code-named Cobalt, known to interrogators as the Salt Pit or Dungeon , which was so forbidding that detainees called it the Dark Prison.
In November 2002, the day after the manager of the jail in Afghanistan had ordered Rahman to be chained hand and foot in a sitting position, he was found dead. Yet four months later, the CIA’s station chief in Afghanistan recommended that the officer be given a $2,500 (£1,600) cash award for his “consistently superior work” and he remained in his position until July 2003.
