Teen Flash Mob Leads to Cancellation of Tinley Park Carnival.
The final day of a carnival in Tinley Park was canceled due to safety concerns after a "flash mob" of over 400 teens gathered and began fighting with each other. Five individuals were cited for public fighting, and a police officer was injured while responding to the situation. Reports of gunshots were unfounded but caused confusion and panic. Another gathering was being planned on social media, leading officials to cancel the event's conclusion.
