Digging into a Cash Machine

The BBC reports that a gang of thieves in Manchester built a hundred foot long tunnel into an ATM machine.

The passageway was about 4ft (1.2m) tall and had been fitted with lighting and roof supports.

Officers believe the people responsible could have spent up to six months digging the passageway.

However, the thieves only escaped with about £6,000 - because the machine had not been re-filled after the New Year bank holiday.
