Brown due in court after arrest

Brown was arrested on 8 February and pulled out of that night's Grammys

R&B singer Chris Brown is expected in court in Los Angeles later after his arrest last month on suspicion of attacking a woman, prosecutors say.

Brown, 19, who is due to appear even though charges have yet to be filed, was quizzed after he rowed with an unidentified women in a parked car.

Singer girlfriend Rihanna has refused to comment on a leaked photo which seems to show her with facial injuries.

She would not comment on the case on police advice, her spokesperson said.

But the 21-year-old was "doing well and deeply appreciates the outpouring of support she has received during this difficult time", the spokesperson added.

The case was presented by police weeks ago but prosecutors asked for more information before deciding what charges, if any, to pursue.

Police said Brown was arrested on 8 February after he and the woman got into the argument in a parked car in the Hancock Park area of Los Angeles, which escalated after they left the vehicle.

Brown and Rihanna both pulled out of that night's Grammy awards, where they were due to perform.

He has since said he was "sorry and saddened" by the incident and was seeking counselling.
