A Toronto police officer who was convicted of one assault – related to the G20 summit four years ago – has been acquitted in a second case.

No evidence was presented by the Crown against Constable Babak Andalib-Goortani, who was charged with using a weapon to assault a blogger at Queen’s Park.

Last month’s pre-trial hearing saw the judge ruling that a photograph apparently showing the officer about to strike the victim – was inadmissible because it could not be authenticated.

The photo was the key piece of evidence against the officer and the Crown had no case without it.

Andalib-Goortani was one of two officers criminally charged in relation to the G20.

He was convicted last year in the beating of protester Adam Nobody –  partly based on videotape evidence.

The constable is appealing his conviction – which resulted in a 45-day jail sentence.
