A blaze which caused severe damage to an empty house may have been started deliberately.
Around 20 firefighters were called out shortly before 10am to tackle a fire in the rear bedroom of the terraced house on Cedar Street, Accrington.
Smoke from the blaze was affecting a number of properties nearby, several of which were evacuated.
The incident was on Sunday, October 21.
John Taylor, spokesman of Lancashire Fire and Rescue Service, said it was a severe bedroom fire and the whole of the first floor and roof space suffered fire and smoke damage.
He added: “It was a pretty major incident. They had four fire engines and crews which tots up to 20 or 22 firefighters. We are looking at the possibility that it was started deliberately.”
Six firefighters using breathing apparatus tackled the blaze from the inside while a triple extension ladder was used to put out the roof fire.
