A car fire in the early hours near Truro was suspected to have been started deliberately.
One fire engine from St Dennis Community Fire Station attended a report of a car fire involving one vehicle at Ladock Wood at 3.55am.
Firefighters used one hose to extinguish the car that was completely burnt out.
Arson is suspected and Devon and Cornwall Police have been informed and are appealing for witnesses.
Officials said such incidents put the public and firefighters at unnecessary risk and tie up resources that could be in demand for other more serious incidents.
