Grandfather accidentally pulled grenade pin from ground

A grandfather who thought he had found a precious silver ring in the ground ran for his life after discovering it was a pin attached to a hand grenade.

John Hill, 67, was with his family scouring farmland with a metal detector when he stumbled across the shiny metal loop.

He pulled what he hoped was an ancient ring from the ground but then discovered the ring was attached to a pin hanging out of a live Second World War grenade.
