A caravan fire discovered by drivers in the middle of a main road last night was started deliberately, say firefighters.
They sent engines out from Tring and Aylesbury to tackle the blaze in Lower Icknield Way, Wilstone Green, just before 11.10pm.
Herts Fire and Rescue Service later said that the caravan had been completely destroyed by the time they had got the blaze under control about 30 minutes later.
