their history, from rushing the field. Violence quickly spread, with fires set in the stadium, pitched battles between hooligans and police, and looting in nearby areas. At least 35 police and 55 civilians were reported to have been injured. On December 21, 2011, a fourth round match in the 2011–12 KNVB Cup between Eredivisie clubs Ajax and AZ at Ajax's home of Amsterdam Arena was marred by a violent fan incident. In the 36th minute, Ajax held a 1–0 lead when a fan ran on the pitch and launched a karate kick from behind at AZ goalkeeper Esteban Alvarado. The player responded by kicking the fan several times before security arrived. When Alvarado was sent off for retaliating against his attacker, AZ left 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 The KNVB rescinded the red card and ordered the match replayed in its entirety behind closed doors on January 19, 2012.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 3-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 a 30-year stadium ban and a lifetime ban from the club and its season ticket list. In 2021, fans of the NHL's Montreal Canadiens rioted on the streets of Downtown Montreal after the Canadiens defeated the Vegas Golden Knights in Game 6 of their best-of-seven series by a score of 3–2 in overtime to advance to their first Stanley Cup Finals since the 1992-1993 season. Fans set off fireworks, flipped and vandalized police cars, assaulted police officers, threw projectiles, and broke other municipal bylaws in the process, which forced the Bell Centre into a lockdown, locking down the 3,500 fans who saw the game live until police gave the all-clear. The situation was also notable for the fact that it happened on Saint-Jean-Baptiste Day (June 24), Quebec's national holiday, in addition to happening less than one month following the end of the first province-wide curfew in Quebec imposed by Premier François Legault in response to the COVID-19 pandemic in Quebec, which lasted from the beginning of January to the end of May of that year. The Canadiens would eventually fall to the Tampa Bay Lightning in the 2021 Stanley Cup Finals in five games, and would finish in last place in the NHL
