This is the shocking moment police ran in to separate a street fight between women that saw a man appear to try to stab one of them with a pair of keys.
Officers rushed in to break up the brawl which was watched by a least a dozen people shortly before 1am on a street corner in Manor Park, East London.
Police tried to calm the situation and were heard shouting 'stay over there', 'move out the way' and 'Slow down, who's been stabbed, where's she been stabbed?'
Detectives then arrested two women in their 20s on suspicion of causing grievous bodily harm and took them to police stations before releasing them on bail.
