NEWTON, Iowa (AP) — A brawl involving 15 inmates at the state prison in Newton has prompted a lockdown of the facility.
Iowa Department of Corrections officials say a fight broke out in the recreation yard at about 10 a.m. Friday.
Tear gas was used to separate inmates and those involved have been segregated from other prisoners.
Some of the prison guards were exposed to the tear gas and one had a few arm scrapes but otherwise staff was not injured. No serious inmate injuries have been reported
Movement of inmates is now restricted to cells except for meals and medical appointments.
All visits at the medium security facility were cancelled Friday but will resume Saturday.
Prison spokesman Fred Scaletta says prison officials are investigating.
