An Internet-based treasure hunt, known as geocaching, caused a bomb scare in West Yorkshire after a local cafe owner reported a suspicious package.
The hidden box was blown up in a controlled explosion after being placed near the cafe, which was forced to be shut down for two hours.
Geocaching participants use GPS and other mobile devices to hide and locate caches around the world. The caches typically contain a logbook to sign or small item to trade.
Police said participants in the growing sport should notify authorities about their cache or avoid hiding them in urban areas.
