MONTREAL Montreal police arrested seven people and continue to investigate after rioters smashed windows and set fires in Old Montreal during a large protest that took place in violation of the 8 p.m. curfew on Sunday evening. A crowd had initially gathered in Place Jacques Cartier, chanting slogans such as Freedom for the Young. However, some present began setting fires in garbage cans and smashing windows of nearby storefronts. Riot police soon moved in, firing tear gas. Small business owners say after everything they’ve been through, this was the last thing they needed. #quebec@CTVMontreal@CTVNews@CTVNationalNewspic.twitter.com/3HlPOP5J2I
