A man was arrested after allegedly directing antisemitic abuse at Jewish passengers, including children, aboard a London bus and claiming he was carrying a knife, the UK’s Jewish Chronicle newspaper wrote Motzoei Shabbos.

The incident reportedly took place Thursday on a bus route passing through Stamford Hill, a London neighborhood with a large Charedi Jewish population of more than 15,000 residents.

Witnesses quoted by the Jewish Chronicle said the suspect shouted at Jewish passengers that it was a “shame Hitler didn’t kill you,” and said they should have been sent to the gas chambers.

London Shomrim said in a statement that “the bus driver stopped the bus and activated the emergency alarm” as bystanders intervened to help the Jewish passengers.

The organization said its volunteers arrived quickly and “swiftly detained the suspect” until police officers reached the scene and took him into custody.

In a statement cited by the Jewish Chronicle, London’s Metropolitan Police said a 50-year-old man was arrested “on suspicion of making threats to kill.”

Police added that although the suspect claimed he had a knife during the confrontation, officers searched him and did not find any weapon.
