The prison had very strict regulations, and severe beatings were inflicted upon any prisoner who disobeyed. Almost every action had to be approved by one of the prison's guards. The prisoners were sometimes forced to eat human feces and drink human urine. The unhygienic living conditions in the prison caused skin diseases, lice, rashes, ringworm and other ailments. The prison's medical staff were untrained and offered treatment only to sustain prisoners' lives after they had been injured during interrogation. When prisoners were taken from one place to another for interrogation, they were blindfolded. Guards and prisoners were not allowed to converse. Moreover, within the prison, people who were in different groups were not allowed to have contact with one another.
