Bieber was arrested back in September following a collision between a minivan and an ATV that led to a physical altercation with a paparazzo. At the time, Bieber tweeted: "There should be laws against what I just experienced. We should have learned from the death of Princess Diana," adding, "I don't have a problem with Paparazzi but when they act recklessly they put us all in danger."

Then-girlfriend Selena Gomez was with Bieber during the incident. "Justin Bieber and Selena Gomez's peaceful retreat in Stratford this weekend was unfortunately disrupted by the unwelcome presence of the paparazzi," Brian Greenspan, Bieber's Toronto lawyer, said back in September.

The National Post reporter Joseph Brean live-tweeted the verdict. See his tweets below:
