The Ministry of Justice says there was a disturbance Thursday night at the Regina Correctional Centre that required action from the Emergency Response Team.
One staff member and inmate were injured during the event that is estimated to have caused damage in excess of $100,000.
The disturbance occurred in a security threat group unit according to the province.
The province believes at this time 13 inmates were involved in the disturbance.
As a result four inmates were transferred to a different facility.
RCMP are investigating the actions of those inmates and will determine whether or not charges will be laid.
