Eight teenagers have been arrested following a huge fire in Bramley which could be seen from Huddersfield.
Police arrested youths from the Armley and Bramley areas overnight as firefighters battled the blaze, which began at around 8.30pm on Bank Holiday Monday.
Huge plumes of smoke from the fire could be seen from Huddersfield, Batley and Holme Moss.
There was so much smoke that nearby residents were told to keep their doors and windows closed.
Two boys aged 14, three boys aged 15, one boy aged 16 and two girls aged 14 and 13 have been arrested, West Yorkshire Police has confirmed.
Det Insp James Entwistle, of Leeds CID, said: "The building is very frail and we expect within the next seven days it will be taken down to protect the safety of the surroundings.
"We expect this may cause some disruption for the next several days and while this disruption is regrettable it is absolutely necessary to ensure public safety.
"We are working hard with partners to minimise the impact of this work and again, I want to thank residents for their co-operation during this time."
