Two men, who are believed to be known the the victim, have been arrested in connection with the death of a woman this afternoon.
The victim, in her 30s, was stabbed to death on London Road in Ewell by a man who got out of a vehicle.
Surrey Police and an air ambulance rushed to the scene at around 3pm.
A man has been arrested on suspicion of murder while a second man has been arrested on suspicion of assisting an offender. The two were not arrested at the scene.
CI Michael Hodder said: ‘This was a tragic and shocking incident in which a woman has lost her life after being attacked in broad daylight. Our thoughts are with her friends and family at this time.
‘At this stage we believe the victim and suspect are known to each other. We realise there will be a number of questions about what has happened which we will try to answer when we can and would ask the public not to speculate.’
A witness told the Surrey Comet: ‘About 2.55pm i saw a black 4×4 mount the curb and a male got out and chased this woman a couple of feet then grabbed her and she fell to the ground.’
The witness said they saw one man then attack the woman.
The eyewitness said members of the public wrapped up the woman and performed CPR.
Hodder added: ‘We have a number of officers in the area to both investigate and support the community following this attack which we believe would have been witnessed by a number of people.
‘If you did witness what happened and haven’t already spoken to officers, or may have dashcam footage I would urge you to do so immediately, by calling 101 and quoting the reference number PR/P19030779.’
