Chris Brown Turns Himself In For Allegedly Assaulting Female

Update: Singer Chris Brown has turned himself into police after an alleged assault of a female victim.

He's been booked into custody.  Bail was set at $50,000.

The rapper is under investigation for an alleged domestic violence felony battery that occurred in the wee hours of Sunday morning near Hancock Park.

According to the victim, she and Chris got into an argument that turned ugly and violent.

Police say the woman in question has "visible injuries and identified Brown as her attacker."

Brown had already left the scene by the time the police arrived.  Identities of victims of domestic battery are never released.

Brown and girlfriend Rihanna were together looking pretty happy a few hours earlier at Clive Davis' pre-Grammy party.

Both of them canceled appearances at the Grammys on Sunday night.
