Justin Bieber is involved in another trouble and this time with a man whom he allegedly attacked and headbutted during the pre-Grammy's party. The alleged altercation took place at the Serafina Italian restaurant in L.A on February 11, 2017.

Police are currently investigating the incident to determine if it is a potential crime and that Justin is reportedly the suspect. If this is the case, it looks like Justin is having a rough week after he has been allegedly indicted also in a crime which happened last year.

According to TMZ, Justin Bieber was reportedly doing "play fighting" with his friend Kyle Massey when he suddenly noticed that a man was recording him. The report added that he asked the man to stop recording him and to delete the video.

However, the man refused to do so and what made the singer got more furious was when the other people around them also started to record as well. That was when Justin reportedly attacked and allegedly headbutted the man.

After the incident, it has been reported that someone called the police but it was not the man whom Justin attacked. When police from the LA County Sheriff's Department arrived to investigate and check the incident, Justin Bieber reportedly left.

There were also photos of the singer showing a cut on his index finger as he exited the said restaurant. It also looked like Justin appeared so angry because his face looked so flustered and red.

But it has been claimed that the victim no longer wants to file and press charges. Even if the man doesn't want to press charges anymore, the investigation will still continue regardless of what and the incident might be considered as a case of misdemeanor battery.

It has been reported that Justin Bieber was in the said restaurant because his good friend was hosting the event. And some claimed that this can be the reason he missed out his Grammy nomination as per Daily Mail.

It can be recalled that Justin got involved in an altercation last 2016 during a Cleveland Cavaliers playoff game in Ohio. Last February 2015, the police report was released and Justin Bieber reportedly named the suspect for allegedly assaulting the man.
