Bradford warehouse blast victims rescued by firefighters
An explosion at a warehouse in Bradford left two people trapped when part of the building collapsed.
The blast happened at Range Storage and Material Handling Equipment in Parry Lane, at about 16:40 GMT.
Two women, aged 19 and 35, were rescued and treated for shock. Forty people were evacuated from nearby buildings.
Initial reports from the fire service indicated a forklift truck had exploded but it is now thought the blast might have been due to a gas leak.
About 25 firefighters were called to the warehouse and a number remain at the scene.
Mark Helliwell, of West Yorkshire Fire Service, said the building is structurally unsafe and investigations will start in the morning.
The Health and Safety Executive has been informed.
Road closures at the junction of Parry Lane and Sticker Lane are expected to remain in place overnight.
Ch Insp Suzanne Akeroyd, of West Yorkshire Police, said: "The cause of the explosion is still being investigated, but is not believed to be suspicious at this stage."
