Two unexploded mortar shells were discovered today on a heath used for tank and combat training during World War Two.

Surrey Police were called to Headley Heath, at 10.15am, after the shells were found during a routine clean-up of the area which is owned by the National Trust.

Officers evacuated the surrounding area and erected a cordon around the area.

Officers from the Explosive Ordnance Depot were called and a controlled explosion took place at 12.30pm to make the shells safe.

Headley, which borders Leatherhead to its west and to the north by Ashtead, is known for its large heath lands leading out towards Box Hill.

It is believed that the heath was once much higher than it is now, but was flattened out by Canadian troops during World War Two so they could use it for tank and combat training.
