The prison was located in the Maliyya neighborhood of Mosul, specifically in the residence and office of the Iraqi member of parliament Wesal Salim, who had rented the house from its owner in 2011. After capturing Mosul in 2014, ISIS seized the building, which consists of two floors and a basement, and converted it into a security base that included a prison and a complaint office. The detainees in this prison included people charged with both general and security offenses. General offenses included fighting, family disputes, debt claims, and other things for which the punishments were a few days in prison or paying a fine. Security charges included spying for the Iraq security forces, working with the local Iraqi police, and being Shia Muslims. Those on security charges were always transferred from here to other prisons. According to former detainees interviewed by the IPM, torture in this prison occurred between midnight and 4:00 am, after which the detainees would return soaked in blood. Jailers used electric drills to puncture the feet, hands, thighs, and fingers of detainees. The witnesses say that the jailer in charge of the prison was a judge from Mosul. He assigned three jailers to each cell, but only one of the three communicated with the detainees. Late in 2016, ISIS evacuated the prison to avoid being targeted by the Iraqi forces, and moved its operations to the Ibn Sina Hospital Prison. After the expulsion of ISIS from Mosul in mid 2017, the building was returned to its owner, who restored it and leased it as an office to an Iraqi member of parliament from Tikrit province.
