Campaigners in Stoke-on-Trent are calling for stronger powers to stop historically important empty properties from being allowed to decay.
Members of the Our Buslem community group cited the derelict Price and Kensington works in Longport which has been on Historic England's At Risk register.
In November, part of it was demolished after surveys showed it was at risk of collapsing and on Tuesday fire crews said a blaze at the site was arson.
Stoke-on-Trent North MP Jonathan Gullis said he would put forward a bill in September to allow owners to face unlimited fines for allowing historic buildings to decay.
BBC Midlands Today has repeatedly tried to contact the owner of the works but has had no response.
