CASEY residents are being warned to turn off their electrical appliances this winter.
The warning comes after two houses were last week devastated by fires caused by electrical faults.
Detective Senior Constable Ray Ross from Cranbourne CIU said people had to make sure all electrical items were turned off when they were not in use.
Last Thursday, a house in Leckie Street, Cranbourne, was damaged after a fire started in a rear room.
Police believe problems with lighting and bad wiring caused the fire.
The owner of the property noticed smoke coming from the room at about 5pm and the fire was contained to that room.
On Saturday night a house in Pentland Avenue, Narre Warren, was gutted when flames quickly spread through the roof and other rooms about 9.45pm.
Police believe a phone charger caused an electrical fault, starting a fire.
