CALIPATRIA, Calif. -- California officials say six prison guards have been hurt in an attack by an inmate at a maximum-security lockup.
Authorities say the inmate, Douglas Compton, refused orders to leave an out-of-bounds area of a yard Thursday at Calipatria State Prison in Imperial County.
When three guards approached him, authorities say Compton stabbed one in the head and face with a homemade weapon. He also allegedly punched two other officers.
Guards used batons, pepper spray and fired a rifle shot to stop the attack.
Compton was treated for facial cuts and moved to another prison. Five correctional officers and a sergeant were treated for cuts, slashes and sprains and released.
Compton is serving 112 years to life in prison for second-degree murder. He could now face a charge of attempted homicide.
