Two men have been arrested after Jewish shoppers were reportedly pelted with gas canisters and had "Hitler is on the way" shouted at them.
The anti-Semitic incident is alleged to have happened at Tottenham Hale Retail Park, north London, at around 7.45pm on Wednesday, while the suspects were in a pick-up truck.
Jewish neighbourhood watch group Shomrim said they had been contacted by one of the victims who claimed a man in the truck also shouted "Heil Hitler", according to reports.
Scotland Yard said a 24-year-old man had been arrested on suspicion of a religiously aggravated public order offence.
It was later confirmed they had also arrested a 22-year-old man accused of the same offence.
Both suspects came forward to the police and remain in custody, the force said.
Anyone with information on the incident is asked to call the police on 101 or anonymously to Crimestoppers on 0800 555 111.
