A knifeman has gone on the rampage in central London and stabbed to death a woman in her 60s and injured five more people in a potential terror attack.
Police were called to Russell Square at 10.30pm last night after the suspect, 19, chased and stabbed pedestrians in the back, side and arms who were left 'screaming and covered in blood' on the pavement.
He was arrested after armed officers Tasered him to the ground and he is now under police guard in hospital. A woman was pronounced dead at the scene and two women and three men were taken to hospital.
The killer's knife was abandoned on the pavement and next to it the body of the unnamed victim remained under a forensics tent overnight and was taken away by ambulance this morning.
Hotel staff on Russell Square, an area always packed with tourists, said the attacker was 'just going for anyone he could see' before he was shot and pinned face-down by police.
Scotland Yard's top anti-terror officer Mark Rowley said this morning that the 19-year-old appears to have 'significant mental health issues' but admitted terrorism could be a motive.
The Met will send scores of armed officers on to the streets of the London this morning - including members of its new elite counter-terror unit - to reassure the public and in case there is a new attack.
Mayor of London Sadiq Khan has called for the public to remain 'calm and vigilant' as police investigate the motive for the stabbings.
