POLICE and military were called to carry out a controlled explosion after an old Second World War explosive was found.

Metal detector Aron Williams was out in Ochrwyth, Risca, when he made the find on Wednesday afternoon.

“I was digging around when I came across something hard and it turned out to be a bomb from the Second World War,” said Mr Williams, 25, of Tyn-Y-Cwm Road, Risca.

“I dug around it and once I saw the circular side of it I knew what it was.

“I rang the police and when the officer came he said it was completely harmless.

“It was a bit of a surprise when I heard the military had been called and that they had had to carry out a controlled explosion.”

Mr Williams said he had been left “shocked” by the incident.

Gwent Police posted on its Facebook page: “We are receiving reports of a loud explosion in the Rogerstone area.

“Please rest assured that this was a controlled explosion of an old WW2 device that had been discovered in a field.

“Police officers and military personnel have been on scene and have now made it safe.”

A spokeswoman for the Gwent force added: “We received a call at 1.06pm on Wednesday, June 14.

“It was believed to be a WW2 explosive so they carried out a controlled explosion as a precaution.”
