Police have arrested a man suspected in a string of robberies in Montreal and Longueuil.
Samuel Duval was arrested Sunday while allegedly trying to rob a store at the Place Versailles shopping mall.
Investigators say the 37 year old used the ventilation ducts on the roof to access the building and it was that technique that allowed police to link him to dozens of other similar crimes.
Duval faces charges of break and enter and theft.
