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.
