The incident was caught on a security camera during the bank job in a small town in the state of Parana.
The thief was guarding the door of the bank while the rest of the gang went inside.
He was seen 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 went to hospital for treatment.
Police are still searching for the rest of the gang.
The robbery happened last week but the footage has now been released by police.
The robber is seen limping out of the bank
