Seven fire crews were called to tackle a blaze inside a derelict building in Wolverhampton.
Police and firefighters descended on the disused Brewbakers building in Horseley Fields, after a passer-by reported seeing plumes of black smoke billowing from the second floor.
A large crowd gathered in the street outside the building while firefighters battled to contain the blaze.
Adam Hodson, who lives in nearby Albion Street, said he had been out to the shops when he saw the fire develop at around 10pm.
He said: "I noticed smoke coming out of the second floor of the building and the inside was bright orange. The police and fire service were fantastic. They were here within a minute and quickly got the fire under control.
Firefighters remained at the scene after dousing the flames in an effort to secure the building.
Crew Commander Martin Mills, from Dudley Fire Station, said: "We took the call at around 10pm and crews were quickly sent out to the scene.
"As always with fires in derelict buildings there is always the possibility of arson, but it is too early to say at this stage."
The old Brewbakers warehouse in Willenhall Road has been empty for more than 10 years.
The firm used to specialise in home and garden furniture and had stores across the Black Country and Staffordshire
Last year a councillor called for more work to be done on the building, citing it as one of the city's main eyesores.
Councillor John Rowley called for a review on how Wolverhampton City Council used its register of disused buildings, such as Brewbakers and the former Sunbeam factory on Penn Road
