A man aboard a bus in Stamford Hill in London shouted at passengers and threatened them Thursday, warning that he had a knife.

The man shouted, “Shame Hitler didn’t kill you” and “You should all go in the gas chambers.” He also threatened to kill Jewish children.

The driver stopped the bus and activated the emergency alarm, whereupon passengers and members of Shomrim, who arrived on the scene quickly, detained the man until police arrived to take the white male into custody.

In a separate incident last month, parents of students at Hasmonean High School for Boys, an Orthodox Jewish school in the London neighborhood of Hendon, received a letter notifying them that a car had jumped the curb in front of the school, forcing students to leap out of the way to avoid getting hurt. The incident is being investigated as an antisemitic hate crime.

The Metropolitan Police Service has asked for the public’s assistance in finding the suspect.

Campaign Against Antisemitism, a British Jewish advocacy group, denounced the rise in antisemitic attacks.

“Attacks on ambulances, suspected attacks on children — there is nothing to which these antisemitic cowards won’t stoop,” the group wrote on X. “What’s so tragic is that nothing surprises British Jews anymore, because all of this was preventable if the authorities had heeded our warnings two years ago and did their jobs.”

“They refused, and now we and our children are paying the price for their stubborn ineptitude,” the group concluded.
