West Ham have issued lifetime bans to five supporters who invaded the pitch during the Premier League match against Burnley on March 10.
The club said it had taken "swift and decisive action" against individuals who were found to have committed "acts of severe violence and physical aggression".
The match was marred by a series of pitch invasions and widespread supporter unrest, with club director Trevor Brooking confirming that co-owner David Sullivan was struck by a coin towards the end of the game.
A club statement read: "Lifetime bans from all West Ham matches, both home and away, have today been issued to five individuals who crossed safety barriers to enter the field of play - a criminal offence that is a severe breach of stadium safety regulations - while a number of individuals have also been banned for life for violently throwing coins or objects with intent to injure or harm on the bridge directly in front of the directors' box."
