Officers arrived at the scene to find six people injured including one woman who died from her injuries a short time later. The condition of the other five is not yet known and police have not yet named or revealed the ages of the victims
The Met said the suspect was detained after being Tasered at the scene of the incident - opposite the three-star Imperial Hotel - at around 10.40pm last night. It is understood police have cordoned off the area and there is a heavy presence of officers and paramedics at the scene.
Paul Hutchinson, a taxi driver, said he passed the incident shortly after it occurred.
‘I 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. You could see the boots sticking out from under the cloth. 'Loads of armed police, cars with lights on and the body on the floor.'
Scotland Yard confirmed the incident is being treated as a possible terror offence.
A spokesman said:
'Police were called at 10.33pm to reports of a man seen in possession of a knife injuring people at Russell Square, WC1. 'Officers attended the scene along with the London Ambulance Service. 'Up to six people were found injured at the location.
