AZ Alkmaar has issued 43 stadium bans after West Ham United fans were abused during their Europa Conference League semi-final defeat.
Several Hammers players faced a group of fans who had targeted an area including their friends and family, who were unharmed.
The Premier League team won the second leg in the Netherlands 1-0 to secure a 3-1 aggregate victory.
The Dutch club stated in a statement that more suspensions could be imposed in the future.
Before taking any action, the regulatory body of European football, Uefa, will analyze the incident reports.
The club stated:
“AZ has now issued 43 stadium bans in response to last week’s disturbances. It concerns visitors who were involved in the misconduct surrounding the European semi-final in Alkmaar.
“It is by no means excluded that even more local stadium bans will be imposed. Apart from this decision from the club, the criminal investigation by the authorities is still ongoing.”
