The Needlessly Elaborate Plan:
... by building a 40-foot tunnel complete with lighting and scaffolding. They didn't just want their tunnel to take them under the ATM; they wanted it to be nice enough to live in.
Who says criminals don't take pride in their work?
The tunnel was discovered when some workmen stumbled upon a disguised trapdoor in a field and opened it to find what they must have initially mistaken for a passageway to Narnia. Soon they realized that the tunnel, which was still unfinished, stopped about 20 feet short of a cash machine. Naturally, police filled it with cement, and the thieves (who were never found) presumably opened the trapdoor one day to find that they'd been seriously cockblocked.
So, were they discouraged to see months of work buried in cement? f**k no. Four years later, they tried again -- except this time, they totally got away with it. By once again digging a tunnel underneath a local Blockbuster (the reports don't specify, but we'll just guess it's the same one, since it's probably the only one left in all of England), they dug through and ran into some concrete. Completely undeterred, they drilled right through a foot of it, got the cash machine, and made a getaway.
