The NBA forward who played at UCLA is alleged to have been involved in a physical altercation with a woman.
Sacramento County Sheriff’s deputies responded to a 911 call in which the woman allegedly had been prevented from talking to the 911 operator. Barnes was booked into the Sacramento County Jail on felony charges of domestic violence.
He posted $50,000 bond and was released.
Deputies found Barnes and a woman both with visible injuries, but took Barnes into custody after determining he had been the primary aggressor, said sheriff's spokesman Sgt. Tim Curran.
Barnes was recently acquired by the Lakers as a free agent.
He is scheduled to be arraigned on Sept. 13, according to authorities.
A UCLA product, he started 58 games last season for Orlando before signing with the Lakers. The well-traveled swingman had played for the Sacramento Kings from October 2004 to February 2005 before being traded, along with Chris Webber and Michael Bradley, to the Philadelphia 76ers.
