Horrific CCTV shows the moment a masked knifeman bursts into a restaurant and stabs a man, before stopping halfway through his brutal attack to film it.
The victim, in his 20s, was chased into the fast food shop on Walm Lane, Willesden, last Tuesday night.
He attempts to barricade the glass door shut, but is overpowered by the attacker, who forces his way in and shoves him to the ground in north west London.
The video records a long blade being plunged several times towards the helpless man’s legs and his torso.
Astonishingly, the hooded thug - wearing a white mask and dressed in an all-black outfit - pauses and begins to film his assault on a mobile phone.
At the end of the CCTV clip, the knifeman is ushered away by another customer who enters the restaurant and the victim is able to stand and walk away.
The stabbing followed a car chase some social media users compared to scenes from Grand Theft Auto.
A motorist was seen pursuing another driver before getting out of his vehicle to knife him.
A Metropolitan Police spokesman said: “Police were called at around 9.06pm on Tuesday, April 1, to reports of a stabbing inside a restaurant in Walm Lane, Willesden.
“A man in his 20s then self-presented to the hospital with stab wounds. His condition is not life-threatening or life-changing.
“It is believed the victim was driving his car when he was followed by the suspect in another vehicle.
“A collision took place, and the victim ran into the restaurant where he was stabbed.
“No arrests have been made at this time. But officers continue to follow all available lines of enquiry.”
