Police are appealing for witnesses after a fatal stabbing in north-west London.
Officers were called to Camden High Street just after 11pm on Thursday and found a man in his mid-20s with a stab injury who was given first aid but pronounced dead at the scene, Scotland Yard said.
A murder investigation has been launched and the road remains closed to traffic, police said on Friday.
The force said it is understood that a number of people known to the victim were present after the attack and urged them to come forward.
The victim's family are yet to be informed, the force added. A second man in his mid-20s was found nearby also with a stab wound and was taken to a central London hospital.
Police said he was in a stable condition and that his injuries were not believed to be life-threatening.
No arrests have yet been made and police asked anyone with information to call them on 101 quoting reference Cad 8865/12Sep.
Alternatively, they can call Crimestoppers anonymously on 0800 555 111. Police said a Section 60 order - which allows officers to stop and search anyone - had been authorised for the borough of Camden until 2.30pm on Friday.
