The alleged attacker in the Russell Square stabbing has been named by sources as Zakaria Bulhan a 19-year-old Norwegian of Somali origin.
He was arrested on suspicion murder after American tourist, Darlene Horton, 64, died when being stabbed in central London on Wednesday night.
Five other people were wounded in the incident, which was initially thought to be terror related.
The Somali-born man accused of stabbing an American citizen to death and injuring five others in the Russell Square attack 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 last night.
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.’
It came as his victim was revealed to be 64-year-old Darlene Horton – the wife of a Florida professor who was due to return to her native America later today.
Retired teacher Ms Horton has spent the last few weeks in the UK with her husband, psychology professor Richard Wagner, as part of a summer study programme and was enjoying her last night in the capital before they planned to fly back to their home in Tallahassee.
However, she was brutally stabbed to death with a kitchen knife at about 10.30pm in Russell Square last night.
The keen tennis player’s last words were ‘he’s still here, he’s still here’ as she tried to warn others of the attacker before she was found in a pool of blood after being stabbed in the back.
She could not be saved, despite the best efforts of paramedics, and was pronounced dead at the scene. Witnesses said her shocked husband sobbed nearby as her body lay sprawled on the pavement overnight.
The Somali-born Norwegian national accused of stabbing Ms Horton to death and injuring five others was said to be suffering possible ‘mental health issues’ when he allegedly launched the shocking mass stabbing.
As well as killing Ms Horton, the knifeman also injured five others including Israeli holidaymaker Yovel Levkowki, 18, who was slashed across the hand as she approached him to offer help after believing he was a victim.
She said she was lucky to be alive after watching the attacker go on to slaughter Ms Horton in front of her eyes.
‘I don’t know if it’s luck or fate but it’s a miracle,’ she said. ‘The woman standing next to me died before my eyes.’
Police said the other victims include a British man who remains in a ‘serious but stable’ condition after being stabbed in the stomach. An American man, who suffered chest wounds, an Australian woman who was stabbed in the back and an Australian man who was stabbed in the chest, were all discharged from hospital today.
