Two live hand grenades were found on a potato production line in Kings Lynn, Norfolk.

Bomb disposal teams were called to the Pinguin Foods plant to carry out a controlled explosion in a nearby field, reports Lynn News.co.uk.

A metallic clanging sound alerted staff on the production line as the potatoes were being washed.

An Army press office spokesman from nearby Colchester said: "They were live grenades and very unstable.

"They were old, and rust had started coming through. They might have looked like potatoes - but I wouldn't like to peel those ones!"
