CONTROVERSIAL singer Chris Brown has been arrested after allegedly attacking a man in the street. Brown was arrested early Sunday in Washington after a fight broke out near the W Hotel, police said, complicating an already snarled legal history for the Grammy Award-winning R&B singer. Brown, 24, was charged with felony assault in an incident that started just before 4.30am local time, Washington D.C. police spokesman Paul Metcalf said on Sunday morning. Chris Hollosy, 35, also was arrested on felony assault charges, Metcalf said. Police believe the two men were together during the incident but said they couldn't confirm any relationship between the suspects. "There was a physical altercation, which resulted in the victim sustaining injuries," Mr Metcalf said. Brown and Hollosy were being held in police custody until Monday, Mr Metcalf said. Chris Brown and ex girlfriend Rihanna at the 2013 Grammy's in February. A man was injured in the fight and reportedly taken to a hospital, police said, but they did not identify him or give details on his injuries. It was not clear whether the victim was taken by ambulance or another vehicle. He had been released from the hospital as of early Sunday afternoon, Mr Metcalf said. The felony charges in the case were based, in part, on the extent of the victim's injuries, police said. Brown's publicists and attorney, Mark Geragos, did not immediately respond to messages left early Sunday. Brown was in Washington to perform Saturday night at an event billed as a "Homecoming Weekend" party at a downtown club. He tweeted about the party Saturday. Howard University spokeswoman Kerry-Ann Hamilton said Sunday that the party was not sponsored by or affiliated with the school, which is celebrating its homecoming. Brown remains on probation for the 2009 beating of his on-again, off-again girlfriend Rihanna just before the Grammy Awards. The photos of Rihanna's bruised face caused outrage among many fans. Brown pleaded guilty to one count of felony assault as part of a plea deal. He received five years' probation and had remained out of trouble until earlier this year, when prosecutors accused the singer of failing to perform his community labor sentence as instructed. His probation was revoked briefly earlier this year after a hit-and-run incident, and he was given 1,000 more hours of community service to perform. Brown, who lives in Los Angeles and is originally from Virginia, has been involved in a number of incidents since the 2009 arrest. He was initially sued for a nightclub brawl that allegedly erupted between his entourage and that of musician Drake, at the time believed to be a paramour of Rihanna. Brown also tussled with singer Frank Ocean and others after Ocean parked in Brown's space at a recording studio in Los Angeles. Ocean said he suffered an injured finger, but no charges were filed. A second man, Sha'keir Duarte, sued Brown, claiming a concussion. Brown's arrest could prompt Los Angeles prosecutors to seek a revocation of Brown's probation for the Rihanna beating and ask a judge to impose additional penalties on the singer, including time in jail or prison. Brown is due back in court November 20 in Los Angeles to update a judge on his probation. Steve Cron, a Los Angeles criminal defense attorney, said prosecutors and a judge may wait to see how the Washington case plays out before taking any action against Brown. "Just the fact that some guy says 'he hit me' doesn't mean he's in violation" of his probation, Cron said. The potential penalties would depend on the exact wording of Brown's sentence, he said.
