Police are appealing for information after a disused farmhouse was set alight and destroyed.
The fire took place at Charity Farmhouse in Goredike Bank, Gorefield, Wisbech, yesterday (Sunday, March 8) between midday and 10pm.
PC Matt Smart said: “It is clear this was a deliberate ignition as the electrics had been disconnected by the owner, therefore an accidental electrical fire has been ruled out by the fire service.
“Fortunately no one was hurt but under different circumstances it could have been fatal.”
A spokesman for Cambridgeshire Fire and Rescue Service said they were called at 9.51pm.
Firefighters arrived to find a fire in a derelict two storey house.
They extinguished it using hose reels and jets and returned to their stations by 2.10am.
Station Commander Jamie Johnson said: “The crews arrived to find a well developed fire with flames coming through the roof of the building.
“They got to grips with it quickly to ensure the fire didn’t spread any further.
“The fire caused significant damage to the structure of the building. The roof and the first floor collapsed as a result, meaning we could not tackle the fire from the inside.”
Anyone with information should contact PC Smart on 101 or Crimestoppers, anonymously, on 0800 555 111.
