Writing on Facebook Stamford Hill Rabbi Herschel Gluck, who is president of Shomrim in Stamford Hill said the rabbi had been "beaten up in a totally unprovoked attack."
He said: "For a government that claims to care about antisemitism, this is another in a long sequence of such incidents where there is no credible response or followup."
The rabbi said it was evidence of how seriously "authorities claim to take" antisemitism and made a demand for "action."
