A shopkeeper who witnessed the knife attack at Leytonstone Tube station in London yesterday has described seeing a victim calling for help on the floor as he was punched and kicked.

Police were called to the east London station yesterday evening after reports that a number of people had been stabbed and a man was threatening others with a knife.

Scotland Yard said officers arrived at the scene within five minutes of the emergency calls and the 29-year-old suspect was restrained and arrested after police discharged a Taser.

Detectives are currently searching a residential address in east London after the "violent unprovoked knife attack", which is being treated as a "terrorist incident".

Graphic footage of the attacks later emerged online showing the knifeman appearing to slash a man in the throat, and blood pooled on the station floor.

Salim Patel, 59, who runs the station shop and saw the attack unfold, said: "I was just at the shop when the train arrived and people came off.

"I heard some shouting, but sometimes drunk people shout. Then I saw the guy attacking the victim, punching him so hard. The victim was screaming 'please somebody help me. Help'.

"Then the attacker started kicking him on the floor. I think the victim was unconscious, he passed out. Then the attacker took a knife out and started stabbing him as he lay on the floor.

"The victim did not shout anything. I think he was unconscious. The attacker was saying something, I couldn't hear what."

One bystander who filmed the scene yelled at the man as he was being restrained by police “You ain’t no Muslim, bruv”, apparently condemning his suspected extremist Islamic ideology.

Needless to say, his quote was quickly picked up online as a message of defiance against terrorism among Muslims and non-Muslims alike.
