YUMA COUNTY, AZ (3TV/CBS 5) -

One inmate is dead and all employees are safe and accounted for after a riot broke out at the Arizona State Prison Complex near Yuma on Thursday night, according to the Arizona Department of Corrections.

It started around 6:45 p.m. when inmates at the medium-security Cheyenne Unit attacked prison workers, the DOC said.

Roughly 600 inmates were involved in the disruption where they threw rocks, set fire to mattresses and other property outside the yard, and broke into the prison health unit, according to the DOC.

The DOC said 26 inmates were transported to the hospital and treated for non-life-threatening injuries, 15 of which have been released and returned to the complex.

One inmate, Adam J. Coppa, 32 sustained fatal injuries during the riot, the DOC said. His death is under investigation. 

Eleven employees sustained minor injuries and were seen at the hospital. All have been released from the hospital and 10 out of the 11 have returned to work.

The prison is still on lockdown as of 10 p.m. Thursday.

The inmates involved in the riot are secured in the fenced recreation yard. The DOC says they are receiving necessary provisions and care. 

The department said it will thoroughly investigate the disturbance and will seek additional criminal charges for any inmates involved in the violence.

The San Luis Police Department and Yuma County Sheriff's Office assisted the Department of Corrections during the incident.
