THE investigation into a suspected arson attack at Tonedale Mill in Wellington has been completed.

But Avon and Somerset Police have been unable to identify who was responsible for the fire on August 5.

A spokesman said: “While satisfied the fire was started deliberately, it has not been possible to identify the offender.

“Historic England and local planning officers have been spoken to, with a view on how they intend to protect the mill, given the cultural importance to Wellington.”
