Laval police say officers were attacked by young concertgoers after intervening in a brawl at an outdoor concert Saturday night.
About 1,000 people had gathered for the concert which was part of a new Moroccan festival near Laurentian Highway 15 and du Souvenir Blvd. said Lieutenant Geneviève Villemure from the Laval police.
Around 8 p.m. a group of about 150 people, mostly between the ages of 15 and 18, erupted into a brawl while rapper Salimo was performing, says Villemure.
When police and security intervened, some of the young concertgoers responded by circling the police and running in and out of hiding spots to throw rocks at the officers.
