Chris Brown to be questioned over alleged punch

R&B singer Chris Brown will be questioned as part of an investigation into allegations that he punched a man during a fight over a parking space in West Hollywood, the Los Angeles County Sheriff's Department said.

Deputies responded to a call on Sunday about a fight involving six men on Santa Monica Boulevard, the department said. Witnesses said the Grammy-winning singer had assaulted a man during the brief altercation.

No arrests were made. The alleged victim was not named in a department statement that said Brown and his entourage had left the scene before deputies arrived.

Investigators plan to contact the singer about the incident at a later time, according to the department.

Brown, 23, is serving a five-year probation sentence after pleading guilty to assaulting fellow R&B star and former girlfriend Rihanna on the eve of the 2009 Grammy awards.
