A Guelph driver says he was shocked when he saw a bylaw officer run a red light in front of him.

On Sunday afternoon, Andrew Brown, 32, was driving to visit his girlfriend when he stopped at a red light in the city's downtown.

In a dashcam video Brown later posted to Facebook, you can see a black car directly ahead of him, and what appears to be a bylaw vehicle in the right lane. Once the intersection is clear, the bylaw vehicle runs the red light.

"I was kind of dumbfounded," says Brown. "I figured that bylaw would know he has to stop, and know how that intersection works."
