OKLAHOMA CITY (AP) — The Oklahoma Department of Corrections announced Wednesday that it has lifted lockdowns at state prisons statewide that were imposed after what was called a “disturbance” at a prison in Stringtown.
All prisons have resumed normal operations, said DOC spokesman Matt Elliot. The statewide lockdown of state and private prisons was prompted by a March 2 disturbance at Mack Alford Correctional Center, about 120 miles south of Tulsa.
There were no injuries to prison staff and no serious injuries to inmates, the department said.
The lockdown was lifted last week for all but six prisons.
The cause of the disturbances is under investigation, Elliott said, and the lockdown was ordered after investigators learned of more potential violence at other state prisons.
All state prisons were locked down in September after an outbreak of apparent gang-related violence left one inmate dead and more than a dozen injured.
