Armed men in masks stole an estimated $6.3 million USD (30 million DKK) in what authorities say is the second largest bank heist in Danish history. Police say six robbers forcibly entered a cash depot in Glostrup, a suburban area in Copenhagen, using a forklift to smash through the building's wall.

According to the International Herald Tribune, the robbers were armed with assault rifles and submachine guns. A number of the depot's employees were in the building when the incident took place, but no one was injured.

Police spokesman Bent Isager-Nielsen said that the robbers left the area using several getaway cars, adding that the criminals spread metal spikes on the roads to evade pursuing police cars. Isager-Nielsen said noted that four police cars responding to the crime scene got flat tires.

CNN said that the robbers left about 2 kilograms (4.5 pounds) of plastic explosives at the depot, as a distraction for police. Officers chased after the robbers, but some were forced to stay behind and cordon off the area in the event of any explosion. Authorities could not immediately ascertain however, if the explosives were meant to explode.

Authorities likened the depot robbery to recent hold-ups in Sweden. Isager-Nielsen said that the police are now coordinating with Swedish authorities as part of the investigation on the incident.

The largest heist in Denmark took place in 2000, when a cash transport was robbed of an estimated 41 million kroner.
