Police have begun a murder investigation after a 17-year-old boy was stabbed in south London.
Police were called at around 4:20 am on Saturday, 20 June, to reports of a stabbing in Battersea following "a potential altercation" on Glycena Road, Battersea.
Officers attended with the London Ambulance Service and London's Air Ambulance and found the teenager had serious injuries.
Despite the efforts of paramedics, he was pronounced dead at the scene. His next-of-kin have been informed and are being supported by specialist officers.
The Metropolitan Police have appealed for witnesses, and are particularly keen to speak to anyone who may have seen a group of men running in Lavender Hill between 4 am and 5 am on Saturday.
No arrests have been made at this stage.
Detective Chief Inspector Brian Howie said: "This is a critical stage of the investigation and I am appealing directly to the public: If you were in the Lavender Hill area between 04:00hrs and 05:00hrs, specifically Glycena Road, Acanthus Road or Pountney Road, and witnessed a group of males running, please come forward.
"Any information, no matter how minor it may seem, could prove crucial. CCTV, doorbell or mobile phone footage may provide vital evidence.
"I would also urge members of the public not to assume that information has already been shared, any detail could be of significant importance to the investigation."
Anyone with information or footage is asked to contact police on 101, quoting CAD 1567/20JUN26. Alternatively, information can be provided anonymously via Crimestoppers on 0800 555 111.
