Pop star Justin Bieber is in trouble with the law again. After his most recent arrest he will reportedly be charged with criminal assault against a limo driver.

The incident in question happened in December when Justin was in Toronto and got into an altercation with his driver.

At the time of the scuffle, one of Bieber's entourage was expected to be under investigation, but TMZ is now reporting that the Toronto police asked to speak to the Biebs himself.

While he was a no show at the time, he is now in Toronto waiting to comply with police.

Sources close to the situation claim that Justin will be "booked for assault, given a citation and released on his own recognizance."

Other sources say three different individuals were interviewed yesterday and they're all pointing the finger at Justin.

Ooof. This is not good for The Biebs.
