The 17-year-old boy who was stabbed to death outside Clapham South Tube stationhas been named as Malcolm Mide-Madariola.
Malcolm was knifed outside the station on Friday afternoon. He later died of his injuries in hospital.
The lead cop in the investigation said there had been an “altercation” between two groups of boys a few minutes before the stabbing. No arrests have been made.
Flowers and tributes have been left for Macolm near the south-west London station where he was attacked.
A friend, who is also 17 and did not want to be named, described him on Saturday as a “sweet” young man with ambitions.
She said: “He was sweet and nice and he always used to message me if he knew I was sad.”
He is believed to be a student at a college near to the scene where he was attacked.
Malcolm’s killing at about 4.35pm on Friday came less than a day after 15-year-old Jay Hughes was pounced on in a “premeditated attack” near a chicken shop in Bellingham, south-east London.
Meanwhile, a man believed to be aged 22 was fatally stabbed in Anerley, south-east London, at about 12.30pm on Sunday.
Det Ch Insp John Massey, of the homicide and major crime command, said: “The stabbing in Balham Hill [where the station is located] followed an altercation a few minutes earlier involving two small groups of young males near to Clapham South Underground station. However, I don’t believe anyone involved had travelled on the Tube.
“There were a large number of people present when emergency services arrived at the scene, and although many have come forward, I want to ensure that we have spoken to all potential witnesses.
“If you were in the area and saw anything suspicious, in particular if you saw an altercation or anything suspicious on Friday afternoon near to Clapham South station, then please call the incident room.”
