Mayura Dissanyake was working the counter at a store when he saw one of his co-workers, who had just gone to the bank, attacked by a group of thugs trying to rob him. What happened next was something the robbers never saw coming.

Instead of getting away with a bag of money, the robbers got an epic beating thanks to Dissanyake who's a semi-professional mixed martial arts fighter.

One of the robbers got such a beat-down he wasn't able to escape. Dissanyake made sure he laid quietly on the ground until the police arrived to arrest him.
