A teenager was punched and had anti-Semitic abuse hurled at him on a bus in north London on Sunday.
The 13-year-old, who was on a bus in the Stamford Hill area, was hit in the stomach by a male, who then shouted: “You stupid Jews think you own the world.”
The incident was reported online by Shomrim, a group which works with communities to tackle anti-semitism and other crimes.
Police are making enquiries over the incident.
A spokeswoman for the Metropolitan Police said the boy’s injuries are not reported as serious.
She added: “Anyone with information that could assist enquiries is asked to contact police on 101 or tweet @MetCC and quote CAD 4968/5Jan.”
Shomrim was founded in New York during the 1970s, with the group establishing patrols in response to high crime rates against the Jewish community there.
The name is Hebrew for “guards”.
Its Stamford Hill group was founded by people from the Orthodox Jewish community in north London.
It organises community safety patrols, a 24-hour hotline, child safeguarding and public information and works on inter-community relations.
The incident followed a string of reports by Shomrim of alleged antisemitic incidents.
The group said a Jewish woman was approached by a man carrying a large knife who they said shouted “f****** Jew” at her.
A Shomrim member followed the man until he was arrested by police, the group said.
It also reported that two men were threatened at 1.15am on Sunday in Fairholt Road, in the Stamford Hill area, by someone who allegedly said: “F*** Jews, run for your lives before I beat you up.”
The group also said a Jewish man was punched in the face by two males on Saturday night in a “completely unprovoked” attack.
