The Baby singer was charged with assault in his native Canada in December, 2013 after Abdul Mohar alleged he was hit around the head when he refused to turn the volume up on the radio.

The alleged incident is said to have occurred after Mohar picked Bieber and his friends up from a nightclub in Toronto.

Bieber, 21, was later charged with assault, but the case was dropped after prosecutors concluded they could not establish, beyond a reasonable doubt, the identity of the person who assaulted Mohar.

Documents filed in court on Friday (27Mar15) report that Mohar is now asking for $850,000 (£531,250) in damages and a restraining order preventing Bieber from coming within 100 metres (328 feet) of him.

A lawyer for the singer, Brian Greenspan, has called the lawsuit "totally without merit," adding in a statement to the Toronto Star, "During the course of the incident, while speaking with the 911 operator, the limousine driver had, in fact, identified his alleged assailant, who was still present, as black. After a careful assessment of the evidence, the Crown attorney withdrew the charge."
