AN investigation has begun into the cause of the blaze which gutted the Silver Tassie in Leven.
Fire crews drafted in from Methil, Thornton and Kirkcaldy took four hours to extinguish the blaze.
The former pub on Linnwood Drive, which has lain derelict for over a year, had been due to be auctioned off in Glasgow.
At the height of the blaze, five fire engines and around 30 firefighters were in attendance.
Two appliances from Methil attended first and soon requestedback-up from Thornton.
Further back-up was then summoned from Kirkcaldy.
While the crews fought to bring the blaze under control, the Mail understands neighbours were asked to shut their windows and doors as a precaution.
ScottishPower and Scottish Gas were also called out to the scene for safety reasons.
Fife Fire and Rescue Service confirmed no-one was inside the Silver Tassie at the time of the fire.
After extinguishing the blaze crews remained on the scene for most of the day damping down the charred remains.
A crime scene investigator has began work on the building, but it is understood a full investigation will not be completed until the building is made safe.
Future Property Auctions intended to sell the former pub at a public auction at the Radisson Blu Hotel in Glasgow.
The building, described as a “substantial self-contained former public house” had a listed guide price of around £70,000.
