Spaniard among injured five in London stabbing frenzy

The Spanish victim is thought to be a man, but no further details of him or his condition have been released as yet.

London Metropolitan Police confirm that the woman who was given emergency medical attention but died at the scene was from the United States, although again, no other details have been given about her.

Sub-commissioner of Scotland Yard, Mark Rowley, says initial fears that the knifepoint attack was an act of terrorism have been ruled out.

The attacker was a 19-year-old Somalian who held Norwegian nationality, and had no known religious or ideological beliefs, nor had he been 'radicalised' by ISIS recruiters.

His frenzied stabbing spree is said to have been caused by serious psychiatric problems he is suffering from.

The knife-wielding youth was tasered at the scene to immobilise him as British police do not carry weapons, and is being interrogated in police custody.

His family is also being questioned.

Scotland Yard had already announced that a further 600 officers would be on the beat in London following the terrorist attacks in France and Germany, and government sources have been quoted as saying it is a question of 'when, not if' a similar act will be staged in the UK.

But London's may Sadiq Khan has called for 'calm' and expressed his support for the victims of the attack and their loved ones.

“I urge the people of London to stay calm and keep on the look out – please report any suspicious activity, because we all have an important role to play as the eyes and ears of the police and security forces in order to protect the city of London,” stressed Khan who, as the son of a Pakistani bus driver and seamstress who grew up in Tooting, is the capital's first-ever Muslim mayor after a long and successful career as a human rights lawyer.
