Drake and Chris Brown Reportedly Involved in Club Brawl Bottles were thrown and at least eight people, including Mr. Brown, suffered cuts and minor injuries when the fight broke out at the W.i.P. club on Vandam Street shortly before 4 a.m., the authorities said. No arrests were made, nor complaints filed. Detectives were reviewing the club's surveillance tapes, interviewing witnesses and going over the records of people who entered that night to determine who might have been responsible for the melee, the police said. A 25-year-old man who was hit in the head and knocked unconscious was taken to Bellevue hospital with a gash to the head, along with two women whose arms and hands were cut, a fire department spokesman, Frank Dwyer, said. The police said two other women were injured and were taken to a different hospital. It remained unknown what prompted the fight. The two pop stars both had bodyguards and large groups of friends with them, crowded into a club that holds 250 people. The police said earlier in the night two men had approached Mr. Brown's table and asked him: "Do you have a problem with Drake?" Then, as Mr. Brown was leaving the club with his girlfriend and a bodyguard, five men stripped off their shirts and confronted him. Some witnesses identified the five men as associates of Drake, but they have not been identified, the police said. Heated words were exchanged, but no punches were thrown. As the talk escalated, bottles were thrown from other parts of the bar at Mr. Brown and the cluster of men around him, the police said. "We are attempting to get the video and the ID-processing equipment to see if we can identify anyone responsible," said Paul J. Browne, the deputy commissioner of public information. A representative for Drake, who was traveling around town with two bodyguards, said he 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," his publicist, Kelly Bush, said in a statement. Detectives have yet to interview Drake. Mr. Brown put out a statement saying he and his girlfriend, Karrueche Tran, "were victims of a brutal attack last night" and had sustained several injuries. He said he was cooperating with the police. Early Thursday, he had published a picture of himself with a deep gash on his chin on Twitter, though he later removed it. Through a publicist, the owners of the club declined to comment. Both Drake and Mr. Brown have dated the singer Rihanna, which led to rampant speculation on hip-hop blogs and radio stations on Thursday that the two men had become embroiled in an argument over her. Those reports are unconfirmed, the police said. Mr. Brown remains on supervised probation after pleading guilty to assaulting Rihanna in 2009 in Los Angeles on the eve of the Grammy Awards, leaving her with a split lip, a black eye and other injuries. The police in Miami are also investigating a complaint against him from a 24-year-old woman who said he stole a cellphone after she tried to photograph him. Drake was scheduled to perform at Saratoga Springs Performing Arts Center on Thursday night in upstate New York.
