was a 'quiet, shy pupil, who was bullied at his London secondary school.
Zakaria Bulhan, 19, moved to the UK from Norway in 2002, and was said to be suffering possible 'mental health issues' when he allegedly began silently stabbing his unsuspecting victims in a busy London street.
His former friends from Graveney School in Tooting, south London, have now revealed how Chelsea football fan Bulhan was a quiet boy who was bullied in the early stages of secondary school.
One friend said: ‘He was quite quiet, but had friends. He was a little bullied but nothing too extreme.’
The alleged killer, a Somali who came to Britain from Norway in 2002, brutally stabbed to death the US citizen and knifed five others including Miss Levkowki, who had been out for dinner with her grandfather.
The suspect was Tasered to the ground by police and pinned down by up to eight officers who were called to Russell Square. He was arrested on suspicion of murder and spent the night in hospital before being moved to a south London police station.
