A murder probe has been launched after a teenager was stabbed to death while walking through a park in broad-daylight in south west London.
Police were called to Crane Park, in Feltham, at around 3.30pm on Tuesday after receiving reports of a teenager suffering stab wounds.
The 18-year-old, who has not been named, was taken to a central London hospital where he later died. A post-mortem examination is scheduled to take place. No arrests have been made.
Forensic teams scoured the area where the body was discovered, 50 yards away from the footpath.
DCI Noel McHugh, from the Met's homicide and major crime unit, has urged anyone who had been in the area at around 3pm yesterday to get in touch with police.
He said: "They may well have seen something which could be of vital importance. I would also like to appeal directly to those that have knowledge of this murder to contact police."
He is the second teenager to be stabbed to death in the capital within 48 hours.
A-level student Alim Uddin, 17, was knifed to death at a eighth-floor flat on the Roupell Park estate in Brixton on Sunday. He went there to collect a second-hand bicycle he had bought for £90.
A boy aged 16 is due to appear before magistrates in Camberwell today charged with Uddin's murder.
His distraught mother Parool told the Evening Standard: "Our children are being killed and nothing is being done. They are dying like dogs."
Anyone with any information on both incidents should call 020 8785 8099 or call Crimestoppers anonymously on 0800 555 111.
