Oklahoma Department of Corrections officials said a partial release for the statewide lockdown placed on all facilities has been authorized.

All five of the agency’s Community Corrections Facilities are returning to normal operations as well as Eddie Warrior Correctional Center, Mabel Bassett Correctional Center, Oklahoma State Reformatory, Bill Johnson Correctional Center, William S. Key Correctional Center, and Oklahoma State Penitentiary’s Maximum-security unit, a news release said Wednesday.

The lockdown was enforced last week after several gang-related incidents, according to ODOC officials.

ODOC said it will determine if the lockdown for the remaining facilities can be lifted Monday, Sept. 13.

“We will return the rest of our facilities to normal operations as soon as it is safe and responsible to do so. The safety of our staff and inmate population remains our top priority,” ODOC Director Scott Crow said.

The agency said visitation will resume Sept. 11

According to the release, the inmates involved in last week’s incidents remain under restrictive housing as the investigation continues.
