THE terrifying moment a suspect creeps up behind his victim before he knifes him has been revealed.
In a cold-blooded attack, the suspect took a knife to his defenceless victim's back amongst a crowd of pub-goers, with no motive yet known.
In the video, a man can be seen casually walking behind the victim before stabbing him several times in the back while crowds chat around them.
Cops released stills of the attacker, while the footage was released on social media.
The Sun has chosen not to show the full footage of the attack.
Emergency services were called to the Fatling Hornchurch pub, in Havering, East London shortly after midnight on 23 July after cops on patrol were alerted to the stabbing.
