No one was located and the RAV4 was ravaged by the fire.

Police attempted to get in contact with the registered owner of the vehicle but so far have been unsuccessful.

Meantime, just after 3am, police and Metropolitan Fire Service crews were called to another car fire at the back of a church on North East Rd at St Agnes.

Firefighters quickly extinguished the blaze but the MG hatch was destroyed.

Police are investigating if the fires were deliberately lit and are asking anyone with information to contact Crime Stoppers.
