This was the story I was thinking of...."Hi-tech treasure hunts, carried out using the internet, are increasingly popular. But the pastime, known as geocaching, caused a bomb scare in West Yorkshire.
It's all supposed to be a bit of fun, websites direct people to thousands of locations across Britain to uncover hidden boxes where they can leave a note or take a souvenir.
But one geocache was mistakenly reported to police as a suspect package - and was blown up in a controlled explosion, in the town of Wetherby."
