A man who died after being stabbed on Primrose Hill has been named as Finbar Sullivan by the Metropolitan Police.
The 21-year-old was found with knife wounds near the viewing point at the north London beauty spot after reports of a fight shortly after 18:30 BST on Tuesday.
Paramedics treated him but he died at the scene. A second man in his 20s was found on nearby Regent's Park Road with stab wounds and taken to hospital, although his injuries were not life-threatening.
The Met appealed for anyone with information, pictures or videos from the scene to come forward. No arrests have been made.
The force said officers were analysing CCTV footage, speaking to witnesses and gathering forensic evidence.
Det Insp Andy Griffin, who is leading the investigation, said: "Finbar's family have suffered a devastating loss and our thoughts are with them as they navigate this very challenging time.
"Our investigation is progressing at pace and we are 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."
