A teenager has been jailed for shooting a 17-year-old in "an act of cold-blooded murder".
David Nyamupfukudza, 19, was sentenced to life in prison with a minimum term of 26 years, for the murder of Sylvester Akapalara.
He is the second man to be convicted in relation to the killing. Earlier this year, Sodiq Adeojo, 20, was also jailed for a minimum of 30 years for the murder.
Sylvester - a budding athlete from New Cross - was shot dead in the Pelican Estate in Peckham in December 2010.
Passing sentence at the Old Bailey, Judge Timothy Pontius said Sylvester "was just one of many victims, mostly in their teens, who have been targeted over the last few years in acts of mindless and appalling violence simply because of their membership or assumed membership of an opposing gang."
Nyamupfukudza was given a 22 year sentence to run concurrently for the attempted murder of one of Sylvester's friends.
