Los Angeles ( CNN ) -- The charge that Justin Bieber assaulted his limo driver in Toronto in December has been dropped . Prosecutors decided there was `` no reasonable prospect '' of convicting Bieber of striking his limo driver on the back of his head , said Brendan Crawley , a spokesman for the Ontario attorney general 's office . The dismissal comes just days after Bieber , 20 , was arrested on a new assault charge in an alleged fight with a minivan driver in Canada . Bieber 's attorneys have been busy this year following three arrests in January , but all of those cases have been resolved now . Trouble seems to pursue the high-profile singer . He 's been accused of trying to take cell phones from people photographing him in public spots , but no charges have resulted after police investigations . His bodyguards have also faced charges and lawsuits after clashes with people following Bieber . Justin Bieber : 'Do n't believe rumors ' The singer settled a drunken driving charge in Miami last month by making a $ 50,000 donation to a youth charity . The plea deal , which reduced the charge to careless driving , requires Bieber to get 12 hours of anger management counseling and attend a program that teaches about the impact of drunken driving on victims . In July , the pop star accepted another plea deal in a Los Angeles vandalism charge connected with the January egging of his neighbor 's house , receiving two years ' probation . He must also complete 12 weekly anger management sessions , work five days of community labor and pay $ 80,900 in restitution to his former neighbor . The Toronto arrest came in late January over an alleged incident a month earlier as Bieber rode in a limousine to a nightclub after attending a hockey game . Bieber was charged with assault and accused of striking his limousine driver on the back of the head several times on the way to the club . The case slowly made its way through Toronto 's criminal court system , ending with Monday 's decision . `` After completing a thorough review and , in consultation with the police , the Crown determined that there was no reasonable prospect of conviction , '' Crawley said . `` Accordingly , the charge against Mr. Bieber was withdrawn . '' Lawyer : Bieber 's 'peaceful retreat ' interrupted . Bieber 's most recent brush with the law came August 29 in Perth County , Ontario , where his father lives . The singer and girlfriend Selena Gomez were riding in an ATV when paparazzi interrupted their `` peaceful retreat , '' according to his attorney Brian Greenspan . `` Investigation revealed that after colliding , the driver of the ATV and an occupant of the minivan engaged in a physical altercation , '' Ontario provincial police spokesman Kees Wijnands said . Bieber 's attorney said people with cameras were chasing the singer when the incident happened . Bieber was released on `` a promise to appear '' and ordered to answer the charges at a September 29 hearing , Wijnands said . The alleged victims hired Los Angeles lawyer Gloria Allred , who also represents a woman who accused Bieber of assaulting her at a Hollywood tourist spot when she tried to take a photo of him with her cell phone . `` This is a serious matter that could have an impact on Mr. Bieber 's probation status in California , '' Allred said in a statement last week to CNN.Â `` I have also made contact on my clients ' behalf with the Hollywood branch of the Los Angeles Police DepartmentÂ to make them aware of these new charges . '' It would be up to a California judge to decide if the Canadian arrest warrants a probation revocation hearing , according to the spokeswoman for the Los Angeles prosecutor .
