A teenager stabbed to death in a row about a borrowed tracksuit was a former pupil at King Solomon High School.
Charlie Kutyauripo, 16, was killed at party at a social club in east London on Saturday evening.
A witness said he was involved in dispute with four other youths over a tracksuit which he had borrowed and failed to return.
Charlie, whose parents are originally from Zimbabwe, had been a student at the Jewish school in Redbridge before leaving to study business at college.
Matthew Slater, headteacher of King Solomon, said the school was deeply saddened to hear of the death of its former pupil.
He said: "Our thoughts are with his friends and family. He was a cheerful student who still has many friends at the school. We are offering support to those that knew him and any pupils affected by the tragic incident.”
Former King Solomon deputy head boy Jodeci Joseph told The Times: “I used to look after some of the younger students and he was one. He was a nice boy, very friendly and very sociable.”
Police investigating the murder have appealed for witnesses.
