An eight-year-old boy was beaten up on his way home and a woman was confronted by a man giving a Nazi salute, according to a new study of anti-Semitic attacks in London.

Other victims targeted for being Jewish include an 11-year-old boy who was told to remove his skullcap or be beaten up, and a group of women chased by teenage girls hurling racist abuse.

Another Jewish woman and her children were jeered by a female who tried to stop them boarding a bus before telling her: “I’m not going to move for you, you Jewish people are selfish, you Jewish people are bad.”

The cases are some of 32 anti-Semitic incidents logged during a month-long study among ultra-Orthodox Charedi Jews living in Stamford Hill.

The Stamford Hill Shomrim, which compiled the data, believes the incidents are “only the tip of the iceberg”.

It said there had been no attempt to encourage reporting of attacks during the study and no significant world or national events that could have led to a rise in anti-Semitism.

Rabbi Herschel Gluck, president of the Stamford Hill Shomrim, said: “These figures are shocking.”

Some of the most disturbing incidents involved boys. In one, an eight-year-old boy in Haringey was assaulted by a man who told him he was a “stupid Jew” before the child ran home crying.

Women have also been targeted.

A 55-year-old woman in Hackney was asked while praying on the Jewish New Year if she covered her hair because Hitler had shaved it off. The offender made a Nazi salute.

In another incident, three Jewish women in Hackney were chased by teenage girls shouting “the Jewish people are rich, horrible Jewish people, give us your money”.

Gideon Falter, the chairman of the Campaign Against Anti-Semitism, said: “Members of the Jewish Charedi community, including very young children, are being singled out and targeted for racist assaults and abuse.

“Under-reporting of anti-Semitism is largely due to the perception that nothing will be done, and that is why the work of Shomrim is so important.”

All of the incidents uncovered during the study have been reported to police.

Most of the suspects were adult males, but nearly a fifth were children under 18. A fifth of the alleged perpetrators were reported to be white, a quarter black and a third Asian.

The figures will fuel concern about a rise in hate crimes in London, partly triggered by the Brexit vote.
