Kawczynski, of north London, was ordered to pay £200 of the penalty to the victim as compensation. The remaining £595 will go to the authorities.
In a statement, Hackney Police Sergeant Owen Pyle said: "This incident shows how seriously the police and courts take antisemitic hate crime. It is unacceptable and we will not stand for it.”
He paid tribute to the work of volunteer security service Shomrim in bringing the offender to justice, saying: “We continue to work closely with the Shomrim and other community groups to tackle antisemitic behaviour towards the Jewish community, and thank them for their assistance in reporting this individual to us."
Chaim Kahan, a Stamford Hill Shomrim spokesman, said: "Hate crime can have a profound and lasting effect on its victims. Such behaviour is simply not acceptable and should not be tolerated. Everyone has the right to be safe and to feel safe within their communities."
