The same building was the target of a similar attack just three days earlier.
According to police spokesperson Jeanne Dourin, similar incidents have recently been reported in the areas of Ville Saint-Laurent and the West Island. Arson investigators will be looking to see if one or more of these events may be linked.
Eclipse officers have joined the arson squad in the investigation. The eclipse section of the force works primarily to combat violent crime in Montreal, and also provides support to other police units.
