Backstreet Boys singer Nick Carter was being held in lieu of $1,500 bail in a Key West, Florida, jail Thursday following an altercation at a bar in the resort town.

According to a Key West Police Department incident report, Carter, who turns 36 on Jan. 28, was arrested on a misdemeanor battery charge Wednesday night after fighting with a bouncer at the popular Hog’s Breath Saloon. A relative of Carter’s, Michael Papayans, 27, was arrested on the same charge for fighting with bar manager Matthew Stecher.

Witnesses said Carter and Papayans entered the tavern “heavily intoxicated,” and became “agitated and aggressive” toward a bartender who refused to serve them. Per the arresting officer’s account of a security video, “Carter and Papayans were asked to leave multiple times,” but were “uncooperative and security was forced to escort them out.” At the front door, one of them threw a punch at a bouncer.

After this, “Bouncers restrained both individuals and released them after both agreed to calm down,” the officer said. Carter and Papayans continued to block the entrance and argue with staff, until Carter threw “what appeared to be a punch” at bouncer Skylar Carden. “Security detained both individuals until I arrived on scene.”

One witness said Carden “extended his arms in an attempt to get Carter out of his face. Carter grabbed him by the throat,” leading other bouncers to take the singer to the ground.

Stecher told police Papayans took off his shirt and head-butted him on the chin.
