WEST HAM'S Israeli international Yossi Benayoun has spoken of his embarrassment at hearing anti-Semitic abuse by some of the club's fans towards Tottenham's supporters.
The English Football Association has launched an investigation into reports of the abuse, while West Ham reacted by banning for life one of two fans cautioned by police at the match at White Hart Lane on Sunday.
Some Hammers fans appeared to mock both the gassing of Jews in the Holocaust and the knife attack on a Spurs fan before Tottenham's game in Rome last week.
Hammers fans sang "Viva Lazio - can we stab you every week?" and hissed on several occasions, apparently mocking the mass execution of Jews during the Second World War.
Benayoun said on Twitter: "I have a great relationship with the West Ham United supporters, from my first spell at the club and again now I am back on loan here.
"This is why I was very disappointed to hear some of the songs yesterday and it was embarrassing."
Police confirmed that two West Ham supporters were cautioned after singing anti-Semitic chants.
The two fans were arrested during the game, police said.
One of those was a Hammers season ticket holder who has since been banned for life. A club statement said: "West Ham 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."
The chants have also been reported to the police by the Society of Black Lawyers.
Tottenham will be submitting video evidence as part of their report to the English 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."
