Police are investigating after eggs were thrown at Jewish worshippers and a synagogue in north west London.
Passengers hurled the eggs from a silver Ford Mondeo during a series of anti-Semitic hate crimes over two weekends in Edgware.
Jewish watchdog, the Community Security Trust, said abuse was also scrawled on a rubbish bin outside a company owned by a worshipper.
Detectives said no one was seriously injured but they were incredibly distressed.
Officers appealed for witnesses to the incidents which took place between March 12 and 18 in the Hale Lane area.
A 20-year-old man arrested on suspicion of racially aggravated assault was bailed pending further enquiries.
A Met spokesman said: “A number of people have already come forward to provide statements and footage of the incidents, but police are keen to hear from anyone else who can assist their investigation.”
