BOMB disposal experts have shared images of a Second World War 'explosive' found at a Dorset quarry earlier this week.

Dozens of people were evacuated from their homes while a controlled explosion took place on Thursday morning at Henbury Quarry in Old Market Road, Corfe Mullen.

The device was unearthed while crews worked to drain off rainwater from the site after a downpour.

After the detonation, it was discovered that the device was an "ordnance prototype and not a viable explosive", a spokesperson from Dorset Police said.

RAF bomb disposal technicians from 5131 Bomb Disposal Squadron estimated that the device weighed around four-and-a-half tonnes.

A spokesperson from the RAF said it was "impossible to tell whether the bomb was still dangerous".

Warrant officer Phil Hunt, the senior explosive ordnance disposal officer at the scene, said: “Safety drives everything.

"In situations like these you must always assume the worst case - that means getting everyone away to a safe distance.

"Dorset Police and the other emergency services have been absolutely great and assisted us wherever we’ve needed it.”

The quarry provided some natural protection for the controlled explosion.

Concrete practice bombs were often used by the British during the war for training purposes.

A 1,000 metre cordon was put in place around the quarry ahead of the detonation.

More than 30 properties and six businesses were evacuated and roads closed.

Group captain Rich Pratley, commander of the RAF A4 Force, said: “Time and again 5131 Squadron has proven itself to be a key military capability.

"Operationally speaking, their expertise is invaluable and at home, as we have seen this week, their skills are irreplaceable.”
