Police say one man was injured during a protest in downtown Montreal Wednesday night.

A group of about 500 anarchist protesters took to the streets, leaving from Emilie-Gamelin Park.

Police say demonstrators launched projectiles at them, causing police to tell the protesters to disperse.

The glass front doors at SNC-Lavalin building on Rene-Levesque Blvd. were damaged by protesters, police said, and more shattered glass was also seen one block west.

Most protesters left the scene by 10 p.m., said police.
