We received a number of different reports, which included a person in the river, a car in collision with pedestrians and a man armed with a knife. Officers were all ready in that location as part of routine policing. But immediately additional officers were sent to the scene and that included firearms officers.

We are working closely with the London Ambulance Service and the London Fire Brigade. We know there are a number of casualties, including police officers, but at this stage we cannot confirm numbers or the nature of these injuries.
