Busted! Police find drugs growing in an old school bus

On I spy a crime we often highlight examples of criminals doing stupid things, like the Dutchman who reported his Ecstasy collection as stolen. Today I've read a story about some crims who seem a little more creative than your average crook.

Three men in North Carolina have been caught growing marijuana plants in, of all places, an underground school bus. The bus was buried eight feet into the ground, underneath a garden shed. Lenoir County Sheriff's Office says they had been looking for the source of the area's marijuana for years and had previously tried spotting the plants using a helicopter. It was only when a police dog fell through a disguised trap door to the bus that the underground loot of 68 plants was discovered.

Usually cannabis factories are easier to spot than this. These days police regularly use heat sensoring technology to detect them from the air, but they still need to be pointed in the right direction by the public. Watch the video below about the tell-tale signs so you can keep your eyes peeled.
