DOUGLAS, AZ (Tucson News Now) - Officers were able to get a reported fight under control at the prison in Douglas.
The incident was originally called a "riot," but on Monday Cochise County officials said :
Two groups of inmates were involved in a large-scale fight, fighting each other, according to Andrew Wilder with the Arizona Department of Corrections. The melee occurred in the prison yard around 7:55 p.m. on Sunday, August 27.
Wilder said 15 inmates and six officers were injured. The officers were injured while trying to break up the fight, and are expected to make a full recovery.
Seven of the injured inmates were sent back to the prison after being treated for their injuries. One inmate remains in critical condition.
Tactical response teams were used to restore order. It took about an hour for officers to get the fight under control. The inmates are now being compliant, Wilder said.
Wilder would not specify the motivation behind the fight, but said that officers were not targeted.
The Arizona Department of Corrections is still investigating why it started.
Wilder explained that the inmate-on-inmate fight occurred in the Mojave Unit of the Douglas Prison. He said that is a "medium custody unit," a dormitory-style facility where the inmates have free access to the yard in the evening hours.
Those units are secure. As of 10:00 Sunday night, inmates were still in the yard and being processed by correctional officers to get them back into their units.
Per protocol, the unit is locked down until further notice, Wilder said. No perimeter breaches occurred.
The names of the inmates involved have not been released.
