An assault charge against pop star Justin Bieber was withdrawn in a Toronto court on Monday, after the prosecutor said there was no reasonable prospect of conviction, local media reported, clearing up one Canadian legal battle for the superstar just as another begins. He was arrested and charged with assault and dangerous driving just over a week ago near the town of Stratford, Ontario, where he grew up. Bieber’s lawyer, Brian Greenspan, said in an emailed statement last week, “Justin Bieber and Selena Gomez’ peaceful retreat in Stratford this weekend was unfortunately disrupted by the unwelcome presence of paparazzi.”
