Fire investigators have revealed a lorry fire which closed part of the A43 heading towards Northampton on Thursday (October 21) was started by MICROWAVE.
Two crews from Northampton rushed to the scene, near Silverstone, at 8.43am and found the flatbed lorry well alight.
The road was closed northbound towards Towcester for up to six hours while the lorry was doused, dampened down then recovered, and a diesel spill cleared.
A Northamptonshire Fire and Rescue Service spokesman confirmed: "The fire was started accidentally in a microwave inside the lorry's cab."
