A teenager has been charged with attempted murder after “shy and loving” business student Jamel Boyce was stabbed repeatedly in a street attack.
He will appear in custody before Camberwell Green Magistrates' Court on Saturday.
Jamel, who studied at St Francis Xavier Sixth Form College, lost the majority of his brain function after he was stabbed in the heart and legs and has not regained consciousness since.
Police believe he will never make a full recovery.
A harrowing image previously released by his family shows Jamel in a hospital bed, forced to breathe through a tube.
His parents Pansy and Patrick Boyce said last month they are faced with “immeasurable grief over losing the boy they knew”.
Two other boys, both 17, arrested after the attack remain on police bail and are next due back on a date in late April, police said.
All other people arrested have been released with no further action.
