Three people were arrested and a gunman is still at large after a fight broke out among adults attending a child's birthday party in a Chuck E. Cheese restaurant in Boynton Beach, Florida. According to Palm Beach, Florida's WPBF, the brawl involved as many as 18 adult men, one of whom shot another man in the leg.

A manager at the restaurant told WPBF that two men exchanged words in the restroom during the party on Saturday. Moments later, up to 18 men where exchanging blows in the restaurant's main dining room in a free-for-all that saw the birthday boy's grandmother thrown to the ground and trampled.
