ARMY bomb disposal experts were called to Pocklington after a man found an unexploded Second World War grenade while out walking his dog.

The grenade was detonated in a controlled explosion but Pocklington police have put out a stern warning to the public not to touch explosives if more are found in the area.

Teacher Nick Longster, of Back Lane, Barmby Moor, found the device while walking his dog on land near Pocklington airfield early on Wednesday.

He said: "I was just walking my dog on a path I walk on quite regularly, as do many other people, when I saw this shape sticking out and I thought it looked like the shell of a hand grenade.

"I scratched round it and realised it was so I moved it to the side of the path, called the police, and went back later with them to show them where it was.

"I was a bit surprised to find such a thing on a path I walk on every day."

PC Chris French, of Pocklington Police, immediately went out to investigate and the army bomb disposal unit from Catterick was at the scene within the hour.

PC French said: "It was a live grenade found on farmland between the airfield and Barmby Moor.

"We are issuing a warning to the public that if they find anything that might be explosives not to touch them and to call the police immediately."

PC French said nothing like this had been found on that site for a long time but it was an active airfield during the war so it was not a complete surprise.
