A 16-YEAR-old boy had a car driven at him before four thugs chased him on foot and stabbed him to death.
Drekwon Patterson was found in the street suffering from stab wounds in Wembley, North West London, at 11.30pm on Thursday.
Cops have released images of a car and a van in relation to the investigation.
They are appealing for information about a car seen driving from the scene which was later discovered burnt out.
Detective Chief Inspector Richard Leonard said: “I need to hear from any witnesses or anyone with information about this tragic murder – if you know anything that may be significant, please get in touch.
“In particular, I need to find out more information about a car – a black Ford Mondeo, using registration number YR54 NHN – which was seen on CCTV driving away from the scene and found burnt out in Silver Jubilee Park.
“I believe this car was used in an initial attempt to injure Drekwon in a collision on Preston Road.
“After the Mondeo had been driven at him, Drekwon ran away and was chased by four suspects who had got out of the car, before being caught and fatally stabbed.”
He said the car is a “key line of inquiry” and described it as “a fairly large vehicle and quite old, so it would have been noticed”.
The officer said police are also keen to trace the driver of a van which was seen on CCTV stopping briefly near the scene.
He said: “I am appealing for that driver to please come forward as a witness.”
Despite the best efforts of paramedics and health workers, Drekwon died shortly before 9am on Friday.
He was treated at the scene before being taken to hospital.
Cops named the teenager and released a picture of him as part of an appeal to catch his killers.
Chief Superintendent Sara Leach, in charge of policing in Brent, said: “It is another tragedy that a boy of just 16 years old has died as the result of a knife crime.
“My thoughts are with his family at this time and my officers, alongside homicide detectives, are doing everything they can to identify and arrest those responsible.”
No arrests have been made and Scotland Yard say enquiries into the circumstances around the killing are continuing.
A spokesman for the force added: “A murder investigation has been launched after a fatal stabbing in North London.
“Next of kin have been informed. A post-mortem examination will take place in due course “Homicide detectives from Specialist Crime are leading the investigation. No arrests have been made. Enquiries continue.”
Anyone with any information is asked to call police on 101, quoting CAD 8167/18Feb.
