WATCH: Man Beat With Chair In Queens Burger Joint Brawl

SOUTH RICHMOND HILL, QUEENS -- An argument inside a Queens fast-food joint turned into a full-on brawl when a trio began throwing fists - and chairs - at two fellow diners, police said.

Cops are searching for the three men caught on tape attacking the 38-year-old men, beaten one with a chair, inside a South Richmond Hill Checkers restaurant in the early hours of May 12.

The on-camera brawl happened at around 4:20 a.m. inside the chain burger eatery at 120-06 Liberty Ave., where the trio punched and kicked the two men following an argument, police said.

Both men had their chains snatched in the beatdown before the trio of attackers fled the burger joint in a dark four-door sedan, speeding east on Liberty Avenue, cops said.

The two men were sent to Jamaica Hospital in serious but stable condition.

Police said the disagreement that led to the scuffle was unclear, but surveillance footage shows two of the attackers laughing while placing an order before abruptly turning around and shoving the men. Shortly after, a man is shown picking up the fast food chain's metal chair and slamming it down on one of the men.

Cops estimated all three of the perps to be around 25 to 30 years old.

Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477).
