A magnet fisherman sparked a bomb scare after pulling an unexploded Second World War device from a riverbed.

Aaron Lewis, 22, was magnet fishing on a quiet stretch of thRiver Severn in Tewkesbury, Gloucestershire, on Sunday morning when he discovered the shell.

Police set up a 160ft (50 metre) cordon around the area before the bomb was destroyed in a controlled blast by an Army explosive ordnance disposal team.

The find was the latest in a string of discoveries linked to magnet fishing, a hobby which involves using powerful, specially-designed magnets to sweep bodies of water for treasure.

Other recent finds have included a rusty sub-machine gun and unexploded hand grenades. In June, Martin Andrews, 43, and his son, Jack, 19, died while magnet fishing in Huddersfield after they fell into a canal.
