An Illinois trampoline park promising “the best high energy, adrenaline fix in Peoria” became the site of a violent melee on Saturday night.

In a video of the brawl, dozens can be seen punching, shoving, stomping, and pulling hair as even more stand and observe, sometimes toppling over each other as they get to a safe distance or jockey for a better view of the fray.

Most appear to be teenagers.

Outnumbered staff at the Elevate Trampoline Park try to break up the fighters and push them out of the building. More free-for-alls break out elsewhere in the lobby, and others spill out into the parking lot as police arrive.

Peoria police dispersed the crowds and combatants until adults came to pick them up, a department statement said.
