The blaze started after someone had set fire to a vehicle on a driveway, in Bishops Way, at around 1:40am. DC Neil Patrick said: It is believed this was a deliberate act which could have had fatal consequences. The fire quickly spread and set fire to a second car which was on the same driveway, destroying both cars as a result, as well as substantial fire and smoke damage to the front of the victims house. I am appealing to anyone who may have witnessed any suspicious activity or unfamiliar people in vehicles in the area around the time of the incident. Please A black Volkswagen was seen in the area around the time of the fire, therefore I would like to speak with anyone who saw this vehicle or are able to help us identify the owner, to get in touch.
