A family of four had to spend the night outside their home after a house fire over the weekend on Ouellette Avenue near Cabana Road in Windsor.
The family wasn't home when the fire ignited in a bedroom in the basement, and died out before they got home.
However, it still caused $100,000 damage.
The family was back in their home on Sunday.
The investigation continues on Monday with an investigator from the Windsor Police Arson Unit.
