This is the moment when a football referee reacts to an assault by a player by getting a gun out during a Brazilian amateur match that turned ugly.
Gabriel Murta is facing disciplinary action after going to the changing rooms to get the weapon and racing back onto the pitch waving it around.
Mr Murta, reportedly a police officer by day, had to be restrained by one of his linesmen as he walked towards the offending players with the handgun.
The shocking incident happened at the weekend during a regional league match in Brumadinho near Belo Horizonte, Brazil's sixth largest city and the capital of the state of Minais Gerais.
