Police Questioned Over Student Protest Video

Montreal police officers supervising a student protest last week are being questioned after a video of the event prompted allegations of aggressive behaviour.

A video of the Jan. 27 protest shows a police officer using a baton on protesters carrying a banner, and shoving a student to the ground.

Two students were injured in the event, held to protest tuition hikes. The video, posted on YouTube, went viral online.

Montreal police spokesman Ian Lafrenière said police found out about the video through Twitter.

"First of all, we've got to question the officers and if you're talking about getting the other side of the story, I think we do have a video for that."

Lafrenière said officers working the protest are being questioned over the weekend.

Some 2,000 students were at the protest.
