Four women stabbed after man goes on knife rampage in car park of suburban London Sainsbury's

Police have today arrested a man on suspicion of attempted murder after four women were stabbed in a Sainsbury's car park, Scotland Yard has said.

Emergency services were called to the supermarket in Hampton, south-west London, at 10.38am and a suspect in his 60s was held by officers armed with Tasers.

Three women were attacked in the car park and suffered wounds to the legs, chest and back - another woman who was also stabbed was found in a nearby house.

One Sainsbury's worker described seeing paramedics surrounding one of the victims giving urgent treatment.

The woman discovered in a nearby property is said to have suffered life threatening injuries and had to be rushed to a nearby hospital by air ambulance. 

A Scotland Yard spokesman said: 'Officers attended and discovered three women suffering from knife wounds.

'The London Ambulance Service also attended and are providing treatment to the women. Their conditions are not thought to be life-threatening or changing at this time.

'A fourth woman who had also suffered knife wounds was subsequently located at a nearby property. She has been taken to hospital where her condition at this stage is thought to be life-threatening. 

'A TASER was deployed during his arrest; but it was not discharged. At this early stage, the incident is not believed to be terror-related'. 

London Ambulance service said four women were treated at the scene for various stab wounds including to the chest, legs and back.

A spokesman said: '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.'
