Brown, 24, allegedly punched the man once in the face, TMZ reports, citing unnamed
The man, who was not a friend of Brown's, allegedly didn't get even one punch in, according to TMZ.
The alleged victim was being treated at a Washington, D.C. hospital on Sunday morning.
Brown is on probation for a 2009 domestic violence incident involving his ex-girlfriend, the singer Rihanna. He pleaded guilty to the brutal attack on his then-girlfriend. Brown allegedly bit Rihanna's ear and fingers, put her in a headlock that restricted her breathing, and threatened to kill her, according to CNN.
An arrest of any kind could land him in jail for violating the terms of his probation.
