LAS VEGAS — Singer Chris Brown faces another battery accusation just days after he performed at an after-party to the weekend's much hyped boxing match, which was also billed as the kickoff to his residency at the Drai's nightclub. Las Vegas police said Brown, 25, is suspected of beating a man who was found at the Sunrise Hospital & Medical Center on Tuesday. The man said he was playing basketball at the Palms Casino Resort when he got into a verbal argument on the court with the singer. He claimed Brown punched him and, as he was preparing to defend himself, another person with the singer also hit him. The man took himself to the hospital where he was treated for non-life threatening injuries and released. Las Vegas police said they went to the hotel after they were called to the hospital but didn't locate Brown. Authorities say they have given Brown the option to sign off on a misdemeanor battery citation or have the case turned over to the Clark County District Attorney's office. — AP
