A man stabbed to death on London's Primrose Hill has been named by police as Finbar Sullivan.
Officers said the 21-year-old died at the popular viewpoint on Tuesday evening after reports of a fight.
Another man, believed to be in his 20s, was found with stab wounds in nearby Regent's Park Road, but his injuries are described as not life changing.
The Metropolitan Police said Mr Sullivan's family are being supported by specialist officers. No arrests have been made so far.
Detective Inspector Andy Griffin, who is leading the investigation, said police were following several lines of inquiry.
"This incident occurred in a busy, public park and there may be many witnesses who can help us piece together what happened," said DI Griffin.
He added: "We are aware of footage circulating on social media around the time of the incident, and urge anyone who has any information, including photos or videos, which could support the investigation to urgently contact us."
London Ambulance Service said in an earlier statement it was called at 6.41pm on Tuesday and sent multiple resources, including an air ambulance crew, but Finbar couldn't be saved.
