Over 40,000 people spent time in the compound during the "junta" regime. Twelve thousand detainees were interned between September 11 and November 7. The field and gallery were used to hold men, while women were held in the swimming pool changing rooms and associated buildings. Locker rooms and corridors were all used as prison facilities while interrogations were carried out in the velodrome. The Red Cross estimated that 7,000 prisoners occupied the stadium at one point, of whom about 300 were foreigners. According to the testimonies of survivors collected by the humanitarian group, detainees were tortured and threatened with death by shooting. Some were shot on the premises or taken to unknown locations for execution.
