DELANO, Calif. — Multiple correctional officers were injured by inmates Monday during two separate incidents.

According to the Bakersfield Californian, two officers were escorting inmate Steven Corotan to his cell Monday morning when Corotan became combative and refused to enter. A CO attempted to handcuff the inmate, but Corotan punched him in the face, knocking him down the stairs.

Corotan’s cellmate, Raul Alvarado, began attacking the officers as well. One officer was transported to a hospital for a sinus fracture. Backup officers used less lethal rounds, batons and pepper spray to regain control. Alvarado was transported to the hospital with a non-life-threatening head injury.

In a separate incident, inmates were leaving the dining hall to go back to their cells when Jesus Vasquez punched a CO in the face and became aggressive with other officers, the publication reported.

Officers used pepper spray and batons, but multiple officers were injured during the fight. The officers are expected to recover. Vasquez was transported to a hospital and treated for facial injuries.

The inmates are serving life sentences with possibility of parole for murder.
