Montreal police are investigating after a fire broke out in a grocery store in St-Léonard in the early morning.

Police say the fire broke out around 4:30 a.m. after an incendiary device was thrown through the window of a small grocery store near the intersection of Bélanger and Lacordaire.

Fire crews quickly put the fire out.

A can of gasoline was found inside the store by the broken window.

The Montreal police arson squad will meet with the owner to see if there is any surveillance video.
