Hampton Sainsbury's stabbing: Four women attacked in supermarket car park
Police do not believe the incident is terror-related
A man has been arrested after four women were stabbed in the car park of Sainsbury's supermarket in West London.
Police arrived at the supermarket in Hampton in Richmond to discover three women suffering from knife wounds to the chest, legs and back.
A fourth female stab victim was later discovered in a nearby property. She was airlifted to hospital by the air ambulance for injuries described by police as life-threatening.
The other three victims were taken by road ambulances to a different hospital with what have been described as non-life-threatening injuries.
A witness, who did not want to be named, told the Evening Standard: "The attacker only went for the women.
"The man ran through and started attacking them. It didn't seem like they knew him it was completely unprovoked.
"One lady is in very bad condition, she had to be air-ambulanced out."
She said the man "appeared to be out of it", on "drugs or crazy".
Tangley Park Children's Centre, which overlooks the scene of the incident, made sure all their children were kept inside until it was safe.
A staff member at the centre said: "It's just such a shock, our parents and children could have been walking to their cars at that time.
"Our sympathies go out to everyone who was hurt and we are really glad none of our families were involved."
A spokesman for the London Ambulance Service said: "We treated four women at the scene for various stab wounds including to the chest, legs and back.
"We took three women as a priority by road ambulance to a major trauma centre in South London.
"The air ambulance took the other woman as a priority to another major trauma centre in Central London."
A man in his 60s was arrested at the scene on suspicion of attempted murder and is being held in a nearby police station.
Police do not believe the incident is terror-related.
