The Hammers have confirmed that they are identifying 200 fans and will be imposing seasonal or life bans on them depending on the severity of their crimes.
A spokesperson for London Stadium partners West Ham United, E20 Stadium LLP and London Stadium 185, said: “An extensive safety and security operation was delivered in and around London Stadium throughout Wednesday’s match with close co-ordination between West Ham United, London Stadium 185 and the Metropolitan Police Service.
“A small number of individuals were intent on becoming involved in disorder and are being investigated, identified and banned from London Stadium as a matter of priority.
“The response of our safety and security teams was measured, fast and effective and we commend our stewarding and response personnel who were called to deal with several incidents of challenging behaviour.
“It must be stressed that the vast majority of West Ham United and visiting supporters have behaved impeccably and we are committed to ensuring that they can continue to support their team in a safe environment.
“We wish to thank the genuine supporters who are behaving impeccably when attending matches at London Stadium for their fantastic support. We wish to assure them that we will work tirelessly to ban those who seek to affect their enjoyment and match experience.”
