Firefighters from Mansfield were called out to the Wilkos car park in the town centre when multiple cars caught on fire this morning (Wednesday 17th July).
One car was seriously damaged and a van and two other cars were partially damaged during the incident, which happened at around 11am.
Nobody was injured in the blaze.
Police also attended the scene and are investigating the cause of the fire.
One theory at this stage is that an electrical or mechanical fault sparked the flames but officers are reviewing all lines of enquiry including checking CCTV.
