If you cast your mind back to last year, you may or may not remember that time Justin Bieber was involved in a scuffle as he was leaving a basketball game in Cleveland.

The pop star was caught on camera squaring up to a (much bigger) man and attempting to grab something from him. Then man is then seen punching him and knocking him to the ground, and the two take several swings at each other as Bieber's crew jump in. Bieber later posted (then deleted) a picture of himself to Instagram captioned: 'Not a scratch on this pretty boy.'

It seems that that wasn't the end of their disagreement, however, as the man in question has filed an assault charge with Cleveland Police after Bieber refused to make a settlement out-of-court, according to TMZ.

The alleged victim says that the fight kicked off after he tried to take a photo of Bieber, who then became violent and went to grab the man's sunglasses.

Although charges haven't been filed against Bieber, the investigation is ongoing.
