Two Pelican Bay State Prison inmates were hospitalized following attacks by other inmates Tuesday and Wednesday mornings, according to prison officials.

According to release from PBSP, the first attack occurred Tuesday just before 9 a.m. in the level 4 B facility. PBSP Lt. John Silvera said involved inmates were ordered to stop but did not, prompting staff to use chemical agents (pepper spray) to break them up.

“The chemical agent had the desired effect,” the release stated. “Both were placed in restraints and medical assessments were completed. The victim of the attack was transported to an outside hospital via ambulance for a higher level of care.”

A weapon was found at the scene and the assailant was held pending investigation.

Just more than 24 hours later, another attack occurred in the same area, with almost identical circumstances reported by Silvera. In fact, the only reported difference was that an officer in the second incident used a baton in addition to the pepper spray.

As of Wednesday morning, the inmate from the Sept. 18 incident returned to the facility in fair condition. The inmate from the Sept. 19 incident is in critical condition at an undisclosed medical facility, according to Silvera. No names of prisoners or staff have been released.

While an ambulance was dispatched to the prison Tuesday for a stabbing victim, prison officials gave no further details about the incidents.

“The facility remains on normal program,” Silvera said.
