LONDON, England (KRON) — A woman is dead and five others were hurt after a knife attack in London’s Russell Square, according to CNN.

Police have detained a suspect. Russell Square is in the central part of the city, near the British Museum.

The condition of the others was not immediately known.

The statement said one man was arrested, and that a police officer had used a Taser stun gun.

Metropolitan Police Assistant Commissioner Mark Rowley told reporters the woman was in her 60s, but gave no other details.

He said the arrested man was 19 years old and in police custody in a hospital.

“Early indications suggest that mental health is a significant factor in this case and that is one major line of inquiry,” Rowley said.

Police said that terrorism was one possible motive behind the attack.
