TORONTO -- The first Toronto police officer to go to trial on criminal charges stemming from the G20 protests has been found not guilty.

Const. Glenn Weddell was charged after Dorian Barton's shoulder was broken on June 16, 2010.

Barton alleged a police officer hit him with a riot shield, knocking him to the ground, and that he was hit several more times, possibly with a baton.

But Weddell -- who pleaded not guilty to assault causing bodily harm and assault with a weapon -- testified the only contact he had with Barton that day was to help him off the ground.

In delivering his verdict today, Justice Gregory Ellies said while he had "concerns'' about Weddell's testimony, he believes the officer would have remembered striking Barton.

He also said the only eyewitness in the case was "unreliable,'' which left some reasonable doubt.
