Authorities in suburban Tinley Park say the final day of a carnival has been canceled after safety concerns emerged following a Saturday “flash mob” that saw more than 400 teenagers gather, with multiple citations reported.
According to officials, the gathering was organized on social media, and when the group gathered at the Armed Forces weekend carnival near the 80thth Avenue train station, they began to run through a parking lot and “fight with each other.”
A Tinley Park police officer was injured while responding to the situation, officials said.
According to the police, five people were charged with public fighting.
Reports of shots fired at the event proved unfounded but caused confusion and panic in the crowd, according to officials.
Officials say another gathering was being planned on social media, prompting them to cancel Sunday’s conclusion of the event.
