The Montreal police arson squad is investigating a fire that broke out in the City of Westmount on Wednesday morning.
The blaze began inside a home on Edgehill Road around 1:30 a.m.
According to police, it appears that someone threw a Molotov cocktail through a window on the ground floor of the single-family home.
Firefighters extinguished the fire, which caused an estimated $50,000 in damages.
Last October, a car at the home was also set on fire, according to authorities.
Officers say no one was home at the time of the fire.
