       Luke Gazzard from Avon Fire and Rescue Service told The Independent the fire had started just after 2pm on Saturday and was still ongoing nearly an hour later.

       He said firefighters arrived within three minutes of being called. At around 3pm, there were around 40 firefighters on the scene to tackle the blaze on the roof, he added.

       Surrounding buildings were also being evacuated as a safety precaution and nearby roads have been closed, Mr Gazzard said.

       We The Curious said it evacuated the venue on Saturday afternoon following a fire alarm triggered by a fire on the roof.

       It said all visitors and staff had been accounted for.
