WATCH: Investigation underway into pepper spray incident caught on video

A video of a man being pepper-sprayed while behind the wheel of his car on a downtown street is now being investigated by city authorities.

Montreal mayor Valerie Plante says she spoke with the city's interim police chief Martin Prud'homme about the video, which has been viewed tens of thousands of times on various social media platforms since it was posted on Sunday.

It shows a black man behind the wheel of a car being confronted by two police officers on Ste. Catherine St. near the corner of Drummond St.

The video, taken sometime on Saturday night, then shows one of the officers pepper spraying the man in the face at close range. A few moments later, he's taken out of his car and handcuffed. The man, indignant, insists he was targeted for honking his horn — something which often happens downtown during Grand Prix weekend.

He also accused the officers of being racist.

It unclear why the officers approached the man, or exactly what happened in the moments before the video was shot.

As the man was being handcuffed, some in the crowd demand the officers' badge numbers. The video ends with one of the officers shooting pepper spray into the crowd.
