This happened yesterday in South Africa in a match between the Golden Arrows and the Kaizer Chiefs. The idiot got by security and found himself on the field/pitch running over 100 meters before he hit referee Lwandile Mfiki with his green vuvuzela.
The incident came after Mfiki had sent off Chiefs midfielder Reneilwe Letsholonyane for a dangerous tackle in the first half, sparking protests from the players and a heated exchange of words between the two benches.
Another idiot also made his way onto the field but he was unable to get to the referee. League officials indicated that both men will be charged with assault. Other than the embarrassment of having been hit with a vuvuzela, Mfiki was fine.
