The incident took place last week in a small town in the state of Parana and the entire robbery was captured on the internal security camera.
The man was holding two guns in the bank's entrance while his two partners took a money bag inside. Everything was going well until he lowered his right arm and shot his own foot.
The thief left the bank limping and was arrested on the same night when he sought treatment in a nearby hospital. Police are still searching for the rest of the gang.
