Guerrero, who came on as second-half sub in the home game, was on his way to the dressing room when an angry fan seemed to have provoked him.

The Peruvian's reaction was sensational as he successfully aimed at the supporter's head with a bottle of water.

HSV chairman Bernd Hoffmann condemned Guerrero's act in an interview after the game, confirming that the incident will not go unpunished.

Guerrero also faces disciplinary action from the German football federation.
