Brown says he was brutally attacked at the club W.i.P. (Work in Progress) in Manhattan's SoHo neighborhood. He claims his girlfriend and other friends also sustained several injuries.
Investigators said a 25-year-old man suffered a serious cut to the head, and two other men and two women suffered minor cuts. Brown's attorney Mark Geragos, who has been with him during the investigation, said Brown was the victim of a brutal attack. Brown needed eight stitches while his body guard needed 18 stitches and suffered a concussion.At least three people were hospitalized. Police are looking through surveillance footage and interviewing witnesses. No arrests have been made and no complaints were filed.
Neither star was at the scene when police arrived at around 4 a.m. The reason behind the fight remained unclear. Both Brown and Drake at one time dated singer Rihanna.
But Drake denied any wrongdoing. A representative for the Canadian rapper said the star was leaving the club when the altercation began.
"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," according to a written statement.
Witnesses say it all started after two men approached Brown's table and asked him whether he had a problem with Drake, and he said, "No." According to police, bottles started flying. Five bystanders suffered cuts, and Brown's bodyguard suffered a serious cut to the head.
Brown took to his Twitter account following the fight, posting a photo of himself with a cut chin. He later removed the picture and other tweets about the incident that included epithets and taunts.
Brown has had several problems over the last few years. He was convicted of felony assault on his then-girlfriend Rihanna. Then in March of last year, Brown went into a rage after an appearance on "Good Morning America." Co-anchor Robin Roberts asked him questions about the attack on Rihanna, and after the interview, he smashed a window in his dressing room.
Regarding the latest incident, Brown's publicist said in a statement, "Chris and his party are cooperating with N.Y. authorities, who are pursuing this incident further."
Brown is still on probation for the 2009 beating.
