NEW YORK (AP) — Singer Chris Brown, his girlfriend and his bodyguard were injured when a dance floor showdown with members of hip-hop star Drake's entourage turned into a bottle-hurling brawl early Thursday at a nightclub, police said.

Brown tweeted a photo of himself with a cut chin, then later removed it, as well as other messages about the fight, including epithets and taunts. A representative later released a statement saying the singer and his girlfriend, model Karrueche Tran, were victims of a "brutal attack."

A representative for Drake said the star was on his way out of the club when the altercation began.

"He did not engage in any activity which resulted in injury to person or damage to property," according to the statement.

Witnesses told police that two men approached Brown's table and asked him whether he had a problem with Drake, and he replied he did not. Later, as Brown was leaving the club, five men met blocked his way on the dance floor and started taking off their shirts and yelling, police said.

At some point during the face-off, bottles started flying. Chief NYPD spokesman Paul Browne said it's not clear whether the bottles were tossed by members of either entourage, or if bar patrons eager to egg on a dispute started throwing them.

Five bystanders, four women and a man, also suffered cuts during the fight at the club W.i.P. in Manhattan's SoHo neighborhood, police said. Brown's bodyguard suffered a more serious cut to the head, but all the victims were released from the hospital later Thursday.
