A fire at a derelict pottery factory site is being treated as arson.
More than 30 firefighters tackled the blaze at the former Wade Ceramics factory on Westport Road, Burslem, Stoke-on-Trent, on Sunday.
Staffordshire Fire and Rescue Service, which was called at 20:10 BST, put it out in about six hours and nobody was reported to have been hurt.
Staffordshire Police said it was treating the blaze as being deliberately started and its investigation was ongoing.
The fire was out by about 02:00 BST on Monday, the fire service said, after they were called to the road following reports of smoke coming from a roof.
Mark Dunn, who lives nearby, told BBC Radio Stoke: "It's dangerous for them, [isn't] it? It just shouldn't be happening.
"But in my opinion [the building] just wants razing to the ground."
The cause was deemed to be deliberate and the investigation was left with police, the fire service said.
