It was a long night for firefighters last night after eight cars were deliberately set alight.
Crews from Dogsthorpe, Stanground and Yaxley, and a water carrier from Ramsey, were called out at 11.26pm last night (Thursday) to the blaze in Straight Drove, Farcet.
They arrived to find a fire involving eight vehicles and workshops which they extinguished using four hose reels.
They had only returned to their stations by 1.40am.
