Three inmates are dead and five others were injured after a “disturbance” at a correctional facility in Oklahoma Saturday, the corporation that runs the prison said.
The 40-minute "inmate disturbance" at the Cimarron Correctional Facility was put down by staff at around 4:39 p.m. local time (5:39 p.m. ET), Corrections Corporation of America said in a statement. No facility staff members were hurt, the company said.
The names of the inmates who were killed and injured were not immediately released.
The facility was on lockdown and inmates were confined to their housing pods Saturday, and an investigation was under way, the company said. The disturbance occurred in one housing pod, the company said.
Cimarron Correctional is a 1,720-bed facility and houses medium- and maximum-security inmates for the state corrections system, the company said. The facility is about 60 miles west of Tulsa.
The Corrections Corporations of America operates four correctional facilities in Oklahoma. It manages prisons and other facilities in 20 states, and calls itself "the nation's fifth largest corrections system."
In June, between 200 and 300 inmates were involved in a brawl at the prison. Eleven prisoners were taken to hospitals after the fight and the facility was placed on lockdown. The fighting occurred among inmates in three separate housing units. No correctional workers were injured, The Associated Press reported.
