Eight inmates were treated for minor injuries Monday night at Methodist Medical Center in Oak Ridge after a melee in the Morgan County Correctional Complex.

Tennessee Department of Correction Spokesman Robert Reburn said all eight were treated and released, and had been returned to the correctional facility early this morning.

A release from Methodist Medical Center indicated extra security measures were put into place to ensure the safety and security of all patients during the time the inmates were being treated. “It was not a lockdown but rather our security officers controlling access to and from the Emergency Department,” the statement said.

Reburn said prison personnel restricted inmate movements in the involved housing areas until an investigation into the incident is completed.
