A police task force team entered the room and freed the doctor, unharmed, from the two inmates, spokesperson Brigadier Billy Jones said.

The two men were arrested. They took the doctor hostage while they were undergoing their weekly medical check-up at 11am yesterday.

They forced their way into the medical room and held the doctor and a nurse hostage.

They later released the nurse. The two allegedly assaulted her. She sustained bruises and minor injuries.

The men had been changing their demands throughout last night. The prisoners reportedly wanted a transfer to a prison in Gauteng.
