A former mill in Ossett is in danger of collapse after a fire destroyed the building.
Crews from the town’s fire station were called to a jeans factory on Queen Street at around 10.40pm last night.
More than 50 firefighters from six stations fought the three-storey blaze at its peak overnight.
Roads through Ossett have been closed by police, from the top of Bank Street to Ossett Green.
Paul Graham, Ossett’s watch commander who was first on the scene, said: “The fire was over three storeys and a basement, it was an old mill with wooden floorboards. It was too dangerous to commit firefighters to the inside of the building so we fought it from outside.
“The mill is practically destroyed and is today in danger of collapse.”
A spokeswoman for West Yorkshire Fire and Rescue Service said the mill was occupied by a clothing company called Fudge Jeans.
