Seven inmates at the North Fork Correctional Center in western Oklahoma have been injured in a disturbance at the prison.
The Oklahoma Department of Corrections says a group of inmates verbally confronted a second group of inmates in a cell pod at the Beckham County prison about 7:30 p.m. Friday.
The incident escalated and one group of inmates brandished homemade weapons during a physical confrontation. Officials say the disturbance was brought under control and the prison was locked down.
Six of the injured prisoners were transported to a nearby medical facility in Elk City and one was transported to a facility in Oklahoma City. No prison staff members were injured.
Corrections Director Joe Allbaugh credited quick action by prison staff members for containing the unrest. The incident is under investigation.
