Police in California are looking to question Chris Brown over allegations the star was involved in an altercation with fellow singer Frank Ocean on Sunday night (27Jan13).

The two stars and their entourages are said to have clashed following a dispute over a parking space outside a recording studio in West Hollywood.

Cops were called to break up the dispute, and Ocean gave his version of events, but Brown had reportedly left by the time the officers arrived at the scene.

A statement released by officials at Los Angeles County Sheriff's Department has now confirmed cops plan to contact Brown to investigate allegations he punched another man during the stand-off. No arrests were made and the identity of the man who was allegedly assaulted was not released.

Brown, 23, is currently serving probation stemming from a 2009 attack on his then-girlfriend Rihanna.
