Chris Brown is being sued by man who claims he was beaten by the singer during a basketball game.

Malcolm Ausbon has filed court documents claiming the "Beautiful People" star and his entourage hit him during a game at 24 Hour Fitness in north Los Angeles last summer. "When Ausbon expressed dissatisfaction with Brown's behavior, Brown threatened to 'kick his ass' and 'put these hands on you.' Additionally, Brown claimed to be a member of the 'Bloods' a street gang engaged in criminal activity, not limited to murder, drugs, extortion and crime," the documents claim.

The filing further claims he tried to leave the scene Chris and his security started to "strike, punch, kick, pull and stomp Ausbon's head and body," resulting in him having to go to hospital.

Chris, 24, has been on probation since his 2009 assault of then-girlfriend Rihanna, which was revoked last December following a fight in Washington D.C. He is currently undergoing a 90-day court-ordered treatment in rehab for anger management issues.

The Los Angeles District Attorney had asked for him to be taken into custody over the Washington assault, but a judge ruled he is better off where he is earlier this month. Both assault cases are ongoing.
