Police are exploring the claims that the pop star Justin Bieber headbutted a man after brawling two bartenders. The Los Angeles County Sheriff's Department said it received a mobile report allegedly involving the 22-year-old singer at around 2 a.m. on Saturday.

There Are Witnesses Who Attest Justin's Involvement

A witness told the police that Justin was tangled in separate disputes with two bartenders at a restaurant on Sunset Boulevard, West Hollywood. The sheriff's sector said: "The witness said he broke up the fight and asked Mr. Bieber to leave. But Mr. Bieber refuses to leave and he remained at the restaurant still.

"The witness specified, a few minutes later, he saw Mr. Bieber quarreling with a fan when Mr. Bieber suddenly headbutted the fan." As per sheriffs said, the witness told police Justin left the scene after his friends pulled him away from the alleged quarry.

Officers interrogated the alleged victim but he declined for medical reasons and did not want to file a police report. There were no visible marks on the man and investigators are continuing to gather evidence, the sheriff's department said.

Club Bartenders Allegedly Triggered The Whole Incidents

A spokesperson for Serafina Sunset, where the alleged fight occurred, sworn of that any of its staff were involved. The restaurant's director of public relations Caroline McBride said: "We know a little bit about the so-called incident at Serafina Sunset with the celebrity Justin Bieber, but we can guarantee that there's nobody from our staff was involved, nor did we call the police for assistance. "We always have lovely involvements with Mr. Bieber whenever he comes to Serafina."

The alleged happening comes a day after police established Justin had been accused of repetitively punching a man at a hotel in Cleveland. Rodney Cannon appealed that he was attacked by the 'Love Yourself' singer along with his bodyguards after a Cleveland Cavaliers basketball match on June 8. Envoys for Justin could not be reached.
