A spokesman for Lancashire Fire and Rescue Service said: “A joint investigation is underway with Lancashire Police.

“We would like to thank our partner agencies and the local communities for your support and understanding during this ongoing incident.”

Footage from the scene showed large flames engulfing the roof of the building on Saturday as firefighters attempted to bring the blaze under control.

Residents were advised to keep their windows and doors closed due to the smoke.

Warbreck Hill Road remained closed between Bispham Road and Devonshire Road on Monday.

A northbound diversion was subsequently in place at the junction from Benson Road and Plymouth Road.

Blackpool Council said the closures were likely to remain in place during rush hour.

“Delays are expected, please plan ahead and avoid the area if possible,” a spokesperson added.

Lancashire Police confirmed a joint investigation was underway alongside colleagues from the fire service.

Anyone with information that could help the investigation should call 101, quoting log number 1529 of June 7.
