This remarkable security video is from inside a box truck traveling at 50MPH. The thieves tailgate it so closely that one of them can stand on the hood, break open the truck doors, climb inside, steal the best stuff in there, then leap back into the pursuing vehicle.
From PostNord Sverige, the Swedish state postal service:
Theft of goods is a widespread problem in the logistics industry, and thieves are becoming ever more cunning. But as a result of comprehensive and thorough preparatory work and good cooperation with the police, PostNord recently succeeded in catching a gang in western Sweden while they were stealing goods – traveling at 80 kilometers per hour. The evidence can be seen on a surveillance film from one of PostNord's trucks.
