LOS ANGELES, United States — Los Angeles authorities say they are investigating a report that Justin Bieber head butted a man during an argument at a Sunset Strip restaurant.

The Los Angeles Sheriff’s Department says a witness reported seeing Bieber fighting with two bartenders at a West Hollywood restaurant and then head butt a patron early Saturday morning.

The department says Bieber and the bartenders had left by the time deputies arrived. The restaurant was not named.

But an investigation proceeds in case the person wants to pursue a case later.

Email messages sent to Bieber representatives were not immediately returned.
