When the Macedonian officials released El-Masri on 23 January 2004, American security officers immediately took him into custody and detained him. El-Masri later described them as members of a "black snatch team." They beat him and sedated him for transport using a rectal suppository. "The CIA stripped, hooded, shackled and sodomized el-Masri with a suppository—in CIA parlance, subjected him to "capture shock"—as Macedonian officials stood by." He was dressed in a diaper and a jumpsuit, with total sensory deprivation, and flown to Baghdad, then immediately to the "Salt Pit", a black site or covert CIA interrogation center, in Afghanistan. It also held CIA prisoners from Pakistan, Tanzania, Yemen and Saudi Arabia.
