Fire crews have begun investigation work at the scene of a major blaze in Blackpool.
At its height eight fire engines were tackling the fire which broke out in a warehouse in Cocker Street on Thursday afternoon.
Fire crews initially believed people may have been trapped inside the building, and a rescue operation was launched.
A spokesman for Lancashire Fire and Rescue said: “Initially the call stated that there was fire coming from a building near an alleyway.
“Two fire crews, one from Blackpool and Bispham attended and when they arrived at the scene requested a further two fire engines to attend as they believed there could have been people trapped inside the property.
“The building appeared to house a workshop on the ground floor with domestic accommodation on the second floor and it was believed that the building may have been used for multiple occupancy.”
Firefighters wearing breathing apparatus entered the building and carried out a full search.
Nobody was found to be inside and the fire was extinguished using two hose reels.
Police, Electricity North West, Blackpool Council and the Salvation Army all assisted with the incident.
Power was temporarily cut to surrounding properties while crews dealt with the blaze.
One fire appliance remains at the scene.
Lancashire Police and Lancashire Fire and Rescue are carrying out investigations.
The cause of the fire is not yet known.
