An appeal has been made for witnesses to an antisemitic attack in which two young Jewish boys were “racially assaulted, verbally and physically”.

The incident took place on Sunday evening in Golders Green, North-West London, at the North Circular Road crossing between Golders Green Road and Brent Street.

Both the police and the North-West London branch of the Shomrim neighbourhood security group were called in the wake of the incident.

Shomrim said its volunteers “had detained the suspect, who was subsequently arrested by the police”.

However, the group said “a man who witnessed the violent attack stopped his vehicle and got out to assist the victims but did not leave contact details with the victims”.

They urged the man to get in touch, saying that his evidence could be “crucial to ensure the perpetrator faces prosecution”.

The man in question, as well as any other witnesses, are asked to call Shomrim’s 24 hour control room, on 0300 999 1234.
