UPDATE (5/10): Friday afternoon, a judge ordered Chris Brown to remain in jail for an additional 131 days after the singer admitted to violating the terms of his probation. Brown's full sentence was extended to 365 days, and the judge acknowledged the 234 days he's served already. Back in March, Brown was dismissed from court-ordered rehab for violating the rules of the establishment and was arrested shortly thereafter.

Original Story: Chris Brown was arrested Friday afternoon in Malibu for violating his probation. According to a statement from the Los Angeles County Sheriff, the singer was "cooperative" when taken into custody at 2 pm. He's being held without bail.

Probation officials confirmed to The Los Angeles Times that they'd submitted a report on Brown's alleged probation violation, but declined to detail what the violation entailed. 

Brown was apprehended at a court-ordered anger management and drug rehab program, where he had been diagnosed as suffering from PTSD and a bi-polar disorder. His probation extends back to the incident in February 2009, when he assaulted then-girlfriend Rihanna. He plead guilty to the felony assault charges that June, resulting in a five-year probation sentence and 1,400 hours of community labor. He still faces charges over an assault charge in Washington.

The Los Angeles Times reached Brown's attorney, Mark Geragos, who declined to make an immediate comment.
