TORONTO -- A Toronto police officer has been sentenced to six years in the shooting death of a troubled teen on an empty streetcar.

Const. James Forcillo was convicted of attempted murder in the 2013 death of 18-year-old Sammy Yatim, which was was captured on a cellphone video that went viral and spurred outrage in Toronto.

In handing down his sentence, Justice Edward Then said that video was "powerful evidence" that what Forcillo said occurred on the streetcar did not happen.

The police officer was acquitted in January of second-degree murder, but found guilty of attempted murder for continuing to fire after the dying teen had fallen to the floor.

His lawyers had argued for house arrest instead of a prison sentence, while the Crown asked for the officer to spend eight to 10 years behind bars.
