A blaze at a disused mill in Bradford may have been caused by arson.
Firefighters remained at the scene of the fire today in Chapel Street.
Around 40 firefighters from across West Yorkshire tackled the blaze after they were called to the five-storey building at 11.42pm yesterday.
An adjoining residential building was evacuated.
The bottom of Leeds Road was closed until 3.30am today.
Arson has not been ruled out as the cause of the blaze is still under investigation.
Firefighters remained at the scene this morning damping down and clearing rubbish from the site.
