Five inmates were injured Friday afternoon in a fight in Cook County Jail's super-max division, officials said.
A fight broke out among detainees at around 1:30 p.m. and was quickly brought under control, Cook County Sheriff’s office spokesperson Sophia Ansari said in a statement. Several weapons were recovered, she added.
Those injured -- four charged with murder and one with armed robbery -- were taken in serious to critical condition to Mt. Sinai and Stroger Hospitals, according to the Chicago Fire Department.
Injuries sustained in the fight included puncture wounds, officials said, and were not thought to be life-threatening.
It wasn't immediately known what led to the incident, which, along with the source of the weapons, remains under investigation.
