Canadian pop star Justin Bieber turned himself in at a Toronto police station yesterday to face an assault charge.

The 19-year-old was charged over an alleged altercation with a limousine driver in December, reports People.

His lawyer told the website "The Toronto Police Service requested that Justin Bieber appear in Toronto today to face an allegation of assault relating to an incident on December 29, 2013. We anticipate that this matter will be treated as a summary offense, the equivalent of a misdemeanor in the United States."

The statement continued "Our position is that Mr. Bieber is innocent. As the matter is now before the court, it would be inappropriate to address the specifics of either the allegation or of our defense at this time."

Police said that during an altercation a passenger hit a limo driver in the back of the head several times adding "The driver stopped the limousine, exited the vehicle and called police. The man who struck him left the scene before police arrived."

The singer last week made headlines when he was charged in Miami with DUI, resisting arrest and driving without a licence. Some of the charges were later dropped.
