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.
A football player in Argentina shot dead a referee after he was shown a red card during an amateur match in the Cordoba province. Local media reports said that after being sent off, the player returned to the pitch with a gun and shot the 48-year-old referee in his head, chest and neck. Police are searching for the accused, who is still at large. Another player was also injured, but was in a stable condition.
