A member of the Muslim community leapt to the defence of Jewish diners after they were punched outside a restaurant in North London last month, police said.
The victims, two Jewish men in their late 30s and mid 40s, were followed by two suspects after leaving a restaurant in Baker Street at around 5.20pm on 23 May, the force said.
The suspects, two masked men in their late teens or early 20s, caught up with the pair at the junction with Melcombe Street and Glenworth Street and punched them.
They also “made remarks that have led police to treat this as a hate crime,” Scotland Yard said.
But a Muslim person swooped in and confronted the suspects, believed by police to be of Asian descent, and offered the victims shelter.
