A teenager has been stabbed to death in West London.
The 19-year-old was discovered fatally wounded near a large number of cars on Logan Place in Kensington at around 3.30am on Sunday.
He was pronounced dead at the scene, becoming the fifth teenager to die from knife injuries in London so far this year.
Met Police detectives are trying to work out whether the death was linked to a house party on nearby Earls Court Road.
A 19-year-old man was arrested near to the scene in connection with the incident. He has been taken to a west London police station where he remains in custody.
Detective Chief Inspector Mark Cranwell said: "While we are in the very early stages of our investigation, we know there was a party at a nearby address on Earls Court Road around the time of this incident.
"We are still working to establish any link, but it does mean the area would have been busy with vehicles and pedestrians at the time.
"I want to hear from anyone who was in the area; did you witness an altercation? Every fragment of information is beneficial to our investigation and I would urge anyone who may know something to contact police immediately."
Anyone with information is asked to contact police.
Police stood guard at two potential crime scenes in the area, with forensics officers appearing to retrieve material from behind a cordon on Logan Place, while a solitary uniformed officer stood at police tape across the threshold of a terraced property opposite.
A woman in the neighbouring property said she only knew of one person living next door, a young man in one of the middle flats.
Another female neighbour, two doors down, said: "My father saw police shining torches around the back of the house last night, he said it was as though they were looking for something in particular.
"It was the middle of the night when it happened."
