This might be one of the most shocking incidents you'll ever see on a football pitch.
A regional game between Amantes de Bola and Brumadinho in Brazil took a sinister turn as a referee pulled out a gun during an argument over a red card.
The official, Gabriel Murta, was surrounded by Amantes de Bola players demanding an opponent be sent off - only to walk off the field and pick up a firearm from the changing roon.
YouTube footage shows the referee, who has now been suspended, returning to the field brandishing the gun and being restrained by his assistant.
