A state inmate is accused of assaulting three correctional officers and a fellow inmate Thursday morning after wrapping a padlock in a T-shirt at the Idaho Maximum Security Institution.
The incident happened around 9:30 a.m. in a recreation area at the prison. The officers were injured while attempting to stop the inmate-on-inmate assault.
The inmate responsible for the assault is 32-year-old Clark Jackson Cleveland, according to the Idaho Department of Correction.
Two of the officers and the inmate who was assaulted suffered serious injuries and were taken to a local hospital by ambulance. The third officer suffered less serious injuries and was taken to the hospital in a state vehicle. None of the injuries are life-threatening, officials said.
