A woman has died and five other people injured in a knife attack in Russell Square, central London.

One of the victims, a woman in her 60s, was treated at the scene but was pronounced dead a short time later.

A 19-year-old man was arrested at 22:39 on Wednesday evening after a Taser was discharged by an officer. The Met said mental health was a "significant factor" in the events.

Paul was at the scene shortly after the attack. He said "I was going for drinks with a friend near the square […] I saw the police cordon, then the armed police, and I thought - this isn't normal."

He added: "The place was covered in police, there must have been seventy or eighty officers of all different forms and ranks there."
