CHAOS AT FAMILY FESTIVAL: 'Teens' Assault Cops, Unleash Bear Spray, Flash Ghost Gun in Suburban Kansas City Nightmare

LEE'S SUMMIT, Mo. — A wholesome family festival in suburban Kansas City turned into a war zone Saturday night as hordes of unruly teens overran the event, beating police officers, blasting bear spray into crowds, and even ditching a 3D-printed "ghost gun" during a chaotic foot chase.

Lee's Summit Downtown Days, billed as a fun-filled celebration with carnival rides, food stalls, and community vibes, descended into repeated fights, assaults, property damage, and total mayhem as large groups of juveniles refused to disperse. It was the third straight year the family event had been hijacked by the same nonsense.

Cops from three agencies, Lee's Summit PD, Jackson County Sheriff's Office, and Missouri Highway Patrol, had to swarm in for mutual aid just to regain control. Firefighters kept rushing back to treat victims gasping from the bear spray.

The madness kicked off around 7:40 p.m. near the carnival area when a juvenile unleashed bear spray on the crowd, sending multiple people scrambling and coughing. Officers later scooped up three cans of the stuff. Throughout the evening, Lee's Summit Fire Department made multiple trips to hose down victims struggling to breathe.

In another wild scene, officers chased down a juvenile and recovered a 3D-printed ghost gun — one of those untraceable, no-serial-number nightmares. Several other juveniles were detained amid the brawls, but they were quickly cut loose and handed back to their parents or guardians. No serious injuries reported to cops or the public, but plenty of scared families got the hell out.

Video circulating online shows absolute bedlam: crowds of young people sprinting through the streets lined with festival tents, physical pile-ons, bystanders filming on their phones, and cops struggling to restrain individuals as panic rippled through the downtown area.

Lee's Summit police had ramped up security this year with more officers, better lighting, camera trailers, private security, shorter hours, and tweaks to the carnival to keep it kid-friendly. Didn't matter. One fight after another kept erupting for hours.

"We do not have to live like this!!!!" one furious local posted alongside the footage, summing up the rage of families who just wanted a normal night out.

Attendees described the horror: friends shoved to the ground and bleeding, parents yanking their kids away from the "beef" that ruined everything.

One local told FOX4 it was just "one incident, one fight, after another."This isn't isolated. Similar teen-fueled disasters have plagued family events across the country, turning what should be safe, joyful outings into no-go zones after dark.

City leaders and organizers promise more "discussions" and safety tweaks for next year. But after three years running, many locals are fed up with the revolving-door justice and the same crowds spoiling it for everyone else. Enough is enough.
