A bank robbery in St. Francis, Wisconsin was foiled when one of the bank's customers decided to tackle the bandit. 'Good Morning America' anchor Juju Chang follows the story as security footage shows a masked gunman threatening a teller when a customer walks up from behind and nonchalantly puts the punk in a sleeper hold.

Narrating the almost comical security camera footage, Chang reports, "The robber tried to run off with the man on his back still and eventually got away, but thankfully with no cash and no injuries involved."
