A man who stabbed a woman in a coffee shop in central London this morning was chased and detained by members of the public, one knocking the knifeman over with his bicycle.
Brave members of the public held the suspect until police arrived at the scene and arrested him on suspicion of grievous bodily harm after the attack that took place on Edgware Road on Thursday morning.
The victim, a woman in her thirties, was treated by paramedics at the scene before being transferred to hospital.
Authorities said that they believe the suspect and the victim were known to each other and that police were waiting for an assessment on her condition.
Armed Police attended the scene but confirmed that no shots had been fired.
Omar Awada, the owner of a shop across the road from where the incident took place, said that a group of men chased the knifeman and held him until police arrived.
Mr Awada said: "He tried to run away but the local guys managed to catch him and they beat him until the police came.
"It was like Tom And Jerry, they were on him right and left..."
A witness described how one man knocked the attacker down with a bicycle, describing him as a "hero".
The witness, who wished to remain anonymous, said: "We heard screaming, we came out, the guy had a knife, he was stabbing the woman repeatedly, maybe five or six times.
"Maybe 30 people or 40 people were chasing him. They used anything in their hands to stop him.
"When people chased him he tried to escape and scare people with the knife, but we had one hero who put him down on the ground. He hit him with his bike."
