The Stockholm Helicopter Robbery

In the early hours of September 23, 2009, a gang of robbers landed a stolen helicopter on the roof of a cash depot in Stockholm, drilled through the roof skylight, and descended to steal hundreds of millions of Swedish kronor. They had planted a fake bomb at a police helicopter facility to delay response. The heist became known as "the helicopter robbery" and inspired the term "helicopter gang" for similar crimes across Europe. Several perpetrators were eventually caught.
