A woman has died after a mass stabbing in central London that police are probing as a possible terrorist attack.
The suspected knifeman was Tasered by police and arrested after injuring up to six people in the incident in Russell Square late on Wednesday night.
"Terrorism is one possibility being explored at this stage," a Metropolitan Police spokesman said.
It is not known at this stage what condition the other persons injured in the incident are in or the nature of their injuries.
Police were called to Russell Square at 10.33pm after reports of a man seen in possession of a knife injuring people.
At 10.39pm a man was arrested and a Taser was discharged by one of the arresting officers, the Met said.
Extra police have been deployed in the area near the British Museum in Bloomsbury to provide reassurance.
The incident occurred in the same area as where one of the 7/7 bombs detonated in 2005. And it comes just hours after the Met unveiled more armed officers in the capital, The Daily Mail reports.
Paul Hutchinson, a taxi driver, told the publication he could see "loads of armed police, cars with lights on and the body on the floor".
"You drove past Russell Square and the road wasn't shut but the pavement was all taped off by police, lots of armed police, lots of cars and the body was just lying on the floor," he said.
"You could see the boots sticking out from under the cloth."
