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 Premier League match of the season.

The Metropolitan Police 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 ruckus follows disorder at the club's final match at their old Upton Park grounds in May, when Manchester United's team bus was attacked.

Four policemen were injured as the coach was pelted with bottles and other objects.

Overall, the behaviour of West Ham fans has improved considerably over recent years - a far cry from the 1970s and 1980s, when a hostile group of supporters known as the "Inter City Firm" brought trouble to away games.

During yesterday's match, West Ham were initially in the lead after two headers from Michail Antonio.

But it all went downhill after Watford managed to score four goals in the space of just 22 minutes.
