Check out these brave souls in Stockholm, Sweden. After spotting a masked man who had robbed a convenience store, they decided to trap him inside the establishment, despite the fact he was armed with a knife that would make Crocodile Dundee jealous.

It seemed like a good plan until the bandit began threatening to hurt people in the store. Afraid he may follow through, the bystanders let him flee.
