Oct 9th 2012
On Saturday, October 6 at about 1:50 p.m., hundreds of inmates started fighting on a medium-security yard. The fighting spread into the dayrooms of two other housing units.
Correctional officers used pepper spray, batons, baton rounds, direct impact rounds and one warning shot from the Mini 14 rifle to stop the fights. Staff from Chuckawalla Valley State Prison, located next to ISP, also responded.
Seven inmates were seriously injured and taken to area hospitals. Three were treated and returned to the prison; four are still hospitalized. One of the four inmates suffered stab wounds. The other three are being treated for swelling to the head, fluid in the lungs, and damage to an ear requiring surgery.
Approximately 100 inmates were treated at the prison for minor bruises and scratches.
One officer was injured when an inmate threw a rock, hitting his leg. He was treated at a local hospital and released.
Staff recovered two inmate-made weapons.
The prison is on modified program, which means inmate movement and programming is limited to facilitate the investigation.
The entire institution has restricted inmate movement to facilitate the investigation.
