The prison was dark at all times, with curtains and painted exterior windows. Loud music was played constantly. The prisoners were kept in total darkness and isolation, with only a bucket for human waste and without sufficient heat in winter months. Nude prisoners were kept in a central area, and walked around as a form of humiliation. The detainees were hosed down with water while shackled naked, and placed in cold cells. They were subject to sleep deprivation, shackled to bars with their hands above their heads. Four of 20 cells of the prison had bars across the cell to facilitate this.
