Investigators say a molotov cocktail was thrown through the window of the Bombay Mahal restaurant around 12:45 a.m. Saturday morning.
The device ignited a small fire inside and caused minor damage to the restaurant, which is located at the corner of Jean-Talon West and Birnam Streets.
Police have no suspects.
Arson investigators are also investigating a second incident involving a molotov cocktail thrown into a house under construction on Collins Road in Côte-Saint-Luc.
There are no known links between the two incidents.
