This is the shocking moment a Brazilian referee runs onto a football pitch with a gun in an apparent effort to restore order after scenes turned violent when an amateur footballer challenged a penalty.
Referee Camilo Eustáquio de Souza, was filmed grabbing the weapon from his bag along with a pair of handcuffs last Sunday, as an angry player, named as Marcos Lopes Vieira, disputed the decision and allegedly punched him in the face.
