A fire which ripped through the top of a former furniture store and caused parts of Accrington town centre to be evacuated, is being treated as arson.
Fire crews were called to the empty warehouse formerly occupied by Barnes Furniture Store just before 7pm on Friday.
People had to be evacuated from the surrounding area and were told to stay away from the area at the junction of Cannon Street and Church Street.
More than 40 firefighters tackled the flames which had started on the first floor and spread to the roof.
Police are treating the incident as suspicious and the fire service is also investigating how the blaze started.
John Taylor of Lancashire Fire and Rescue Service said: "It's a possible arson. The fire started in the first floor area of the three-storey building. They used an aerial ladder cherry picker to get above the fire and put it out."
He added: "When you get a large fire there is a lot to sift through in terms of forensic evidence. When the fire was out they didn't go inside as there was a risk of collapse so a building inspector used the aerial ladder to run an inspection."
Three crews from Hyndburn Fire Station and one from Great Harwood attended the incident.
The empty building was once home to the Ritz cinema and was also occupied by Barnes Furniture for 30 years until its closure in 2005.
