From Wiki:

December 21 – In the 36th minute of a fourth round match in the 2011–12 KNVB Cup between Eredivisie clubs Ajax and AZ at Amsterdam Arena, Ajax held a 1–0 lead when a fan ran onto the pitch and launched a karate kick from behind at AZ goalkeeper Esteban Alvarado, who responded by kicking the fan several times before security arrived and arrested the fan. When Alvarado was sent off for retaliating against his attacker, AZ walked off the pitch, and the match was abandoned.

The KNVB rescinded the red card and ordered the match replayed in its entirety behind closed doors on January 19, 2012; Ajax was also fined €10,000 for failing to prevent the fan (who was supposed to be serving a three-year stadium ban) from entering the pitch, and given a suspended one-match spectator ban (not including the replay). Ajax accepted the penalties, and announced that it had given the fan an additional 30-year stadium ban and a lifetime ban from the club and its season ticket list.
