TORONTO - Closing arguments are scheduled for today at the trial of a Toronto police officer facing charges arising from the G-20 summit protests three years ago.

Constable Glenn Weddell testified he didn't hit or shove a man he's accused of assaulting, but other officers might have.

Weddell told court the only contact he had with Dorian Barton on June 26th, 2010 was to help him up off the ground.

Barton's shoulder was broken that day and he alleges a police officer hit him with a riot shield, and that he was hit more than once, possibly with a baton, before being dragged away.

Video of Barton's arrest begins with the now 32-year-old Toronto man on the ground and shows two officers helping him up.

Then one of them gives Barton a shove and Barton appears to trip over a curb and fall to the ground.

Weddell says he doesn't know how Barton got on the ground the first time, but the only time he touched him was to help him up.

Superior Court Judge Gregory Ellies will likely give his decision on Friday.
