The home team lost on Saturday to Watford
An investigation has been launched after a number of West Ham fans clashed with stewards and Watford supporters during a home game at London's Olympic Stadium.
The club says those identified as being involved in the crowd trouble will be given lifetime bans, as it has a "zero tolerance" policy to disruptive behaviour. Some West Ham supporters even ended up fighting each other as the Hammers lost 4-2 in their second home Premier League match of the season.
The Metropolitan Police in London have said that no arrests were made as a result of the violence. In a statement, the club added: "West Ham unreservedly condemn the behaviour of the individuals involved in incidents during (Saturday's) fixture against Watford.
"While these isolated incidents were quickly brought under control, this behaviour has no place in football and West Ham will work tirelessly to eradicate such incidents."
West Ham said it is prepared to request the courts serve banning orders on disruptive fans. The team lost 4-2 to rivals Watford and lie in 17th place in the Premier League.
