A BLAZE extensively damaged the first floor and attic of a Keighley house.

Firefighters from Keighley, Bingley and Silsden tackled the inferno, at a terraced property in Redcliffe Street.

When crews arrived at the scene, they had to force entry to the property and it was unclear whether anyone was inside the smoke-filled house.

After a search, it was found to be unoccupied.

Six breathing-apparatus sets were worn and two hose reels used to bring the fire under control.

Two special high-pressure fans were also brought in, to help clear fumes.

Smoke had seeped into the neighbouring properties, which were evacuated.

The fire had started in a bedroom.

Neighbours raised the alarm at about 5.20am today.

Watch commander Michael Rhodes, of Keighley Fire Station, said: "When we arrived there was smoke billowing from an upstairs window.

"The first floor was well alight.

"We'd received the call as a 'persons reported', so there were possibly occupants inside, and a full search was carried out."

Crews spent about two-and-a-half hours at the scene.

The cause of the fire is still under investigation.
