A LIVE hand grenade which could have exploded at any second was found outside a supermarket.
Neil Lodge held the unexploded device, for a minute before dropping it and running to safety.
Bomb disposal experts from the Ministry of Defence were called and safely detonated the grenade outside Asda, on Asdale Road, Durkar.
Mr Lodge, 46, said: “When the bomb squad arrived they said it was a live grenade that could have gone off at any minute.”
He had been searching for objects with his metal detector for a couple of hours before he stumbled upon the grenade – which was capable of killing him and nearby shoppers.
The father-of-two from East Avenue, Horbury, said: “I got a good signal so I started digging. I saw the top of it and dug a bit more.
“I picked it up and stared at it for a couple of seconds before I realised what it was so I dropped it and ran like hell.”
He immediately alerted the security guards at the busy superstore. They called the police who had to draft in army-trained experts from Catterick in North Yorkshire.
Usually Mr Lodge finds medieval artefacts such as coins and pottery.
He said: “I was really shocked when I realised what it was. I remember looking at it in my hand – and it could have exploded there and then.
“Where I found it there is a public footpath with people walking up and down it all day.
“I won’t be going up there again.”
Sgt Jamie Kitchen, of Wakefield police’s response unit based in Normanton, was first on the scene.
He said: “The Ministry of Defence bomb disposal unit carried out a controlled explosion. Thankfully no-one was injured.”
