Ben Austin said he and his son, Finley, were magnet fishing in the River Mole from a bridge in Dorking, England, when their magnet attached to a metal object in the water.

I thought 'this is a bomb.' My son was trying to grab it and pull it up and I said, 'no, this is a real bomb,'" Austin told SurreyLive. Austin called 999 and was asked to text photos of the object to police. Officers advised him to get a safe distance away from the object while a bomb disposal unit was summoned to the scene. He said the experts detonated the magnet, as it was still attached to the explosive, but the experience made it worth the $25 purchase. "I was happy to let the magnet get blown into smithereens," he said.

The explosive device was taken away by a Defense Forces team.
