A man has filed a police report alleging a security guard working for Justin Bieber punched him twice in the face after he tried to take a photograph of the singer.

The Baby hitmaker was at Fluxx nightclub in San Diego, California on Sunday (22Feb15) when he was spotted in the V.I.P area by Steven Prince, who approached him hoping for a photo.

Prince tells Tmz.com a security guard screamed at him and began shoving him, and he has since filed a police report about the incident.

Sources tell the website's editors that the official allegedly involved did not work for Bieber and had been hired by the club's bosses.
