A school spokesman said: "Any loss of life is tragic. When it comes at such a young age it is even harder to accept. This was a popular young man with a bright future, our thoughts go to his friends and family. We are all in a state of shock as we try to come to terms with what has happened.
"We are working with the young man's closest friends to identify how best to commemorate his young life. Our thoughts are also with the girl involved who remains in hospital. Clearly there is a lot of sadness within the school and we would request to be left alone to deal with this."
