A bumbling suspect tried, and failed, to commit an overnight arson at a Mr. Puffs pastry shop on Boulevard L'Acadie in Ahuntsic-Cartierville.

According to police, the suspect broke the window on the shop's back door -- but before lighting his molotov cocktail, he came face-to-face with employees still in the shop after hours. 

The suspect fled in a vehicle and left the incendiary device on the premises. 

Montreal police will investigate the situation further. No suspects have been arrested.
