It's only January, and Justin Bieber has already been arrested twice this year. The Associated Press reports that the 19-year-old singer turned himself in today after being charged with assault for allegedly hitting a limo driver in the back of the head several times.

Police say the altercation happened late last month when the driver picked up Bieber and five others from a Toronto club. During an argument as they rode to a hotel, one of the passengers hit the driver. The official statement says that, "The driver stopped the limousine, exited the vehicle and called police. The man who struck him left the scene before police arrived."

Bieber entered the station surrounded by fans and was inside for about 90 minutes before leaving via a back exit. He is scheduled to appear in court on March 10. His Canadian attorney, Brian Greenspan, declined to comment. But his California-based legal representation, Howard Weitzman, says the Biebs is innocent. "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," he said in a statement.

Earlier today, Bieber pleaded not guilty in Miami to charges of DUI, driving with an expired license and resisting arrest. His arraignment is scheduled for Valentine's Day. The singer has been in the news more lately for his tussles with the law than his music, prompting a White House petition to revoke his green card. His latest struggles include an egg throwing incident in Los Angeles, a scuffle with a paparazzo, damaging property with graffiti and the pet monkey German authorities say he abandoned.
