London’s police force has been forced to issue two apologies after officers threatened to arrest an “openly Jewish” man if he refused to leave the area around a pro-Palestinian march because his presence risked provoking the demonstrators.

Gideon Falter, chief executive of the Campaign Against Antisemitism, was wearing a traditional Jewish skullcap when he was stopped by police while trying to cross a street in central London as demonstrators filed past on April 13.

One officer told Falter he was worried that the man’s “quite openly Jewish” appearance could provoke a reaction from the protesters, according to video posted by the campaign group. A second officer then told Falter he would be arrested if he refused to be escorted out of the area because he was “causing a breach of the peace.”
