LAS VEGAS - Chris Brown is accused of beating a man at a casino just days after performing in Las Vegas over the weekend.

Las Vegas police say the singer is suspected of battery after a man went to a hospital early Monday.

The man told officers he was playing basketball at the Palms Casino Resort when he got into an argument and Brown punched him. The man says he was defending himself when another person with the singer also hit him.

The man was treated and released.

Police say they've given Brown the option to sign a misdemeanour battery citation with a promise to appear in court, or face prosecution by the district attorney's office.

Authorities say Brown has not responded.
