RCMP say fire in St. Albert, northwest of Edmonton, is suspicious

ST. ALBERT, Alta. - Police say they are using dogs to scour the scene of a suspicious house fire in St. Albert, northwest of Edmonton.

The dogs are looking for any signs of flammable liquids.

RCMP say the fire has been deemed suspicious because the fire department was not immediately able to determine a cause of the blaze.

They say a man was at home at the time of the fire and needed to be taken to hospital for treatment.

The rest of the family that lives at the home was on vacation.

Firefighters were able to keep the fire from damaging any of the neighbouring houses.
