A CNN crew filming a book release on Oxford Street in London suddenly got lucky when four riders on two motorcycles smashed the window of a jewelry store and grabbed as much valuables before making their escape. Although the guys look like amateurs, they actually planned the heist pretty well. For starters, it didn’t take them long and the highly revved engines covered the sound of the shop windows as they were broken with a sledgehammer.

The police was soon on the scene, but neither the helmet wearing riders nor the bikes have been identified yet.
