A woman understood to be in her 30s has been stabbed to death in broad daylight on Bank Holiday Monday.
Police rushed to the scene at Stockwell Park Walk in Brixton, south London just after 4pm after a woman reportedly received a stab wound to the neck.
She was later confirmed to have died.
Paramedics from the London Ambulance Service and the air ambulance were also at the scene, reports MyLondon.
A nearby resident told the newspaper: "She was being resuscitated by doctors at the scene but they stopped attempts. The police had cordoned off the area so [there was] no one else around."
A number of roads in the area were closed throughout the afternoon as officers continued to carry out enquiries.
One aerial photo shows medical kits, a police officer's hat, and blue plastic gloves strewn across the cobbles surrounding a blue tent erected at the scene.
Others on social media described seeing police officers seal off entrances to a block of flats as they conducted enquiries.
Several people were seen at the scene later in the evening as one woman, who did not want to be identified, told the PA news agency: "It's still so raw.
"The family are on their way here now and we still need to tell them what's happened. It's just so raw."
A spokesperson for the Metropolitan Police confirmed that the victim's family had been informed and would be supported by specialist officers.
