Crews from Sawtry, Stanground, and Dogsthorpe were called to a house fire in New Road, shortly after 5pm. A derelict two-storey house was alight, including both floors and the roof space. Firefighters used jets and hydrants to extinguish the fire. A water carrier from Ramsey also attended. A spokesman for Cambridgeshire Fire and Rescue Service said: The property was destroyed in the blaze. At 6.40pm the incident was scaled down and firefighters extinguished hotspots. Crews returned to their stations by 8.40pm. A crew continued to return to the property overnight to check for hotspots and dampen down areas. The cause of the fire is believed to be deliberate. Anyone with information should contact police on 101 or Crimestoppers anonymously on 0800 555111.
