Clubbers on a night out were herded into a strip club when a man with a huge knife tried to stab another male in the street.
Terrifying footage shows a fight breaking out in Shoreditch, East London.
As people shout and run along Hackney Road, a man holding a giant blade approaches another male on the floor and tries attacking him.
A woman can be heard screaming "No, no, no, please" as the attacker slashes at the man prone on the floor near Browns lap dancing club.
A man who appears to be a bouncer repeatedly shouts for the victim to get inside as he tries to protect people from the knifeman.
The clip, posted on Twitter with the caption "London is lost", attracted many comments.
"This is awful," a social media user said.
"Hackney Road was where we drank in the 60s, when it was safe to talk the streets of London," a person wrote.
"This knife thing is genuinely terrifying," another commented.
Mirror Online has contacted the Met Police for comment.
