A 19-year-old man has been stabbed to death in west London.
The victim was found on Logan Place in Kensington at around 3am on Sunday.
He is the 13th person to die of a knife attack in the capital this year.
Police said another 19-year-old man was arrested near the scene “in connection with the incident” and is being questioned.
Officers were alerted to the scene after receiving reports of a large number of vehicles in the area.
A murder investigation has been launched and detectives are trying to establish whether the attack is related to a house party in the Earls Court Road area.
Detective chief inspector Mark Cranwell said in a statement: “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.”
There were 80 fatal knife attacks in London in 2017.
