Real-Life Heist Features Helicopter, Rooftop Break-In & Explosives

It sounds like the plot of the latest action thriller. But in what authorities say was a real-life heist today, masked gunmen reportedly used a stolen helicopter to fly onto the roof of a cash depot maintained by a British security firm in Sweden. Once there, they allegedly used explosives to break into the building and stole bags of money.

Police responding to the multi-million-dollar robbery in the country's capital city of Stockholm were unable to do so by air, because apparent explosives had been planted at their helicopter hangar, recounts the Associated Press.

"Meanwhile," reports the Guardian, "a police SWAT team was seen desperately trying to enter the cash depot with a battering ram."

The New York Daily News says the robbers also put spikes on roads near the building to slow down responding police.

The robbers used automatic weapons to hold some 20 employees inside the facility at bay, according to the articles. No one was injured in the pre-dawn raid, which lasted about 20 minutes.
