LOS ANGELES (AP) -- Authorities say R&B singer Chris Brown is being held without bail on a warrant issued by probation officials.
The Los Angeles County Sheriff's Department says Brown was taken into custody at 2 p.m. on Friday and is being held without bail at a downtown Los Angeles jail. The department says Brown was cooperative when arrested.
The 25-year-old is still under court supervision for his 2009 attack on then-girlfriend Rihanna and had been ordered by a judge to remain in rehab since November. He was arrested in Washington, D.C., in October after a man accused the singer of hitting him outside a hotel.
An email message sent to his attorney, Mark Geragos, was not immediately returned.
