The officers were injured after an incident in Division 9, the jail's super max division, in a tier for problematic detainees who engage in sexual misconduct, said a spokeswoman for the Cook County Sheriff's Office. The inmates in that tier are issued specially designed jumpsuits, which they attempted to light on fire by using the microwave to ignite a wick.
This resulted in smoke in the living unit. Two officers were transported for smoke exposure and two others transported for injuries sustained while trying to secure the tier, the sheriff's office said. All injuries are non-life-threatening and the officers were released Sunday, the sheriff's office said.
Video of the incidents was released on Monday.
