More than 100 inmates took over a section of the City Justice Center in downtown St. Louis, injuring a corrections officer at the facility, officials said.
The incident began around 2:30 a.m. Saturday on the fourth floor of the jail, according to the St. Louis Post-Dispatch.
Jacob Long, the spokesman for Mayor Lyda Krewson, told NBC News that the situation is ongoing.
Police and firefighters were at the scene and closed the area surrounding the building, NBC affiliate KSDK reported.
The group of about 115 prisoners threw items out of broken windows and started a small fire inside the jail, Long said. They also flooded floors and clogged toilets, according to the Post-Dispatch.
Long told KSDK that it was a “very dangerous disturbance.”
Chairs and other items were scattered across the street and at least one car had a shattered windshield, the outlet reported. Several of the inmates were seen holding signs and chanting.
A male corrections officer was injured during the incident and taken to the hospital in unknown condition.
As of Friday, there were 633 inmates at the Justice Center. Police told KSDK that all of the inmates are secured inside the building.
