Police have made an arrest after Shomrim reported a woman running after Jewish children with a knife and allegedly shouting “I want to kill all you Jews” in Stamford Hill, home to Europe's largest Charedi community.

Shomrim, the strictly Orthodox neighbourhood watch group, alerted the Metropolitan Police to the incident which took place on Craven Park Road, north London, at 9pm on Sunday.

A police spokesperson said: “Police were called to Craven Park Road, N15 at 2104hrs on Sunday, 17 June to reports of a woman in possession of a knife behaving erratically.

“Police attended and the woman, aged 47, was arrested on suspicion of a racially aggravated public order offence.

“At this time, the female remains in custody at an east London police station. She is expected to undergo a mental health assessment in due course.”

The incident is not terror related, police added.
