West Ham have handed lifetime bans to two fans who invaded the pitch during their 3-1 carabao Cup defeat to Tottenham on Wednesday at London Stadium.
The first incident came before Spurs’ third goal, with the second shortly before the final whistle.
Both fans were also arrested and charged by the police.
West Ham released a statement saying: “Encroaching the pitch is a criminal offence that will not be tolerated by the club,”.
The Hammers will to London Stadium’s operators as they try to determine how the fans got on the pitch.
West Ham who are tenants at the stadium are still waiting to hear if they will be sanctioned by the Football Association for an earlier incident involving crowd trouble and pitch invasion against Burnley in March in which five supporters were given lifetime bans after the incident.
