North Fork Correctional Facility, Sayre, Oklahoma
October 11, 2011

Prisoners take over the private facility, run by the Corrections Corporation of America, after several fights break out on the prison yard. Prisoners barricade themselves inside various parts of the prison and destroy prison infrastructure.  Guards set up a morgue on the yard using a tent, though there are no fatalities. Twelve prisoners are airlifted to a hospital for severe injuries, while more than 30 suffer injuries are treated on-site.

The cause and duration of the unrest is unclear.
