Firefighters from Papworth were sent to a bin on fire in Toseland Road shortly before 2am. On arrival they found a motorhome and a garage, measuring 10 by 8ft, in flames and called for back up from St Neots and Huntingdon. The motorhome contained a gas cylinder so the crews used a ground monitor, a hose fixed to the ground, to cool the cylinder. A fire investigation showed the cause of fire was deliberate and a spokesman for the fire service said that the police had been informed. The crews returned to their bases by 4.35am. INFORMATION: Anyone with information should contact Cambridgeshire police on 101 or Crimestoppers, anonymously, on 0800 555 111.
