West Ham have handed a lifetime ban to a supporter following racist behaviour at Tottenham Hotspur on Sunday, according to a statement on the club's official website.
"Tottenham Hotspur have confirmed that five supporters were arrested during Sunday's match at White Hart Lane outside of the stadium for unrelated incidents and two more were cautioned for racially aggravated gesturing inside the ground. One of those fans has since been identified as a Season Ticket holder and has, this afternoon, been sent a letter containing a banning order from the club. Any other individuals identified can expect a similar swift and robust response."
The Football Association have begun an investigation into reports of racist chanting by West Ham fans at a match against Spurs at the weekend. It said:
"The FA governance department has this morning contacted both clubs and will continue to make enquiries into the matter in the coming days. We note the statement issued by West Ham and encourage clubs to identify and ban for life any individuals involved in incidents of abusive chanting.
"There is no place for anti-Semitism or any form of discrimination in football. The FA is committed to working with the clubs, Leagues, fans groups, the police, CPS and community stakeholders to play our part in addressing this unacceptable behaviour."
Tottenham will be submitting video evidence as part of their report to the FA. A club spokesman said: "We are currently compiling a full report for the Football Association and shall be submitting this with all our evidence including relevant CCTV footage."
Jewish groups condemned the racist chants and urged that those responsible should be punished.
The Board of Deputies of British Jews said: "Anti-Semitism has no place in football or society in general.
"For football fans to use Holocaust imagery and chants glorifying Adolf Hitler is grossly offensive to the Jewish community and is a stain upon the character of British football. This in the same week that Tottenham fans were attacked in Rome in an apparently anti-Semitic attack."
The group referred to another incident in which Scunthorpe United manager Brian Laws compared his team's defending to the Holocaust. He has since apologised.
"Events at White Hart Lane yesterday and comments on Saturday by the Scunthorpe United manager describing his team's defending as being 'as bad as the Holocaust' confirm that this phenomenon is not confined to the Continent," the Board of Deputies of British Jews said.
"We will be writing to the Football Association to urge them to punish those responsible for these chants and to take further steps to rid our national game of these slurs."
West Ham said it will take "the strongest possible action" against any supporters found to have been involved in "inappropriate chanting".
A statement on the club's website said: "West Ham United are in contact with Tottenham Hotspur to assist them with their investigation into the conduct of a small number of supporters and alleged inappropriate chanting during yesterday's match at White Hart Lane.
"West Ham United will take the strongest possible action against any of their supporters, including enforcing life bans from the club, that are found guilty of behaviour which is categorically not condoned by West Ham United.
"During the 46 games in the Championship last season, West Ham United had zero arrests for racism or violence, so while we are surprised to see such reports today, we will examine any available evidence of such conduct thoroughly and take the appropriate action."
Two West Ham United fans have been cautioned by police for singing anti-Semitic chants during yesterday's match against Tottenham Hotspur. A section of Hammers supporters appeared to mock the gassing of Jews in the Holocaust during the Premier League game at White Hart Lane, which Spurs won 3-1
The pair of fans were arrested during the game and accepted the police cautions, Scotland Yard said.Spurs have a large fan-base from the Jewish community. The abuse came four days after Spurs fan Ashley Mills was stabbed in an attack by Italian hooligans before Tottenham's game against Lazio in Rome
West Ham supporters sang "Viva Lazio" and "Can we stab you every week?", as well as the hissing sounds alluding to the Holocaust gas chambers. There were also reportedly chants about Adolf Hitler during the match.
"Two men were arrested during the football match between Tottenham Hotspur and West Ham on Sunday November 25 on suspicion of a racially aggravated public order offence.The men accepted a police caution."
