Video footage shows the moment a terror suspect ploughed into a group of cyclists in a car before crashing into a security barrier outside parliament.
A camera on a nearby rooftop filmed the Ford Fiesta veering left into a cyclists who were waiting at traffic lights before hitting pedestrians.
The car comes to a stop after slamming into the barrier outside the House of Lords.
Armed police swooped on the car and arrested the driver, a man in his late 20s, on suspicion of terror offences.
The footage was broadcast by the BBC as Scotland Yard confirmed the crash is being treated as a “terrorist incident”.
It shows the silver Ford Fiesta travelling along the road next to Parliament Square before moving to turn right towards Westminster Abbey.
As an ambulance passes the car on its right-hand side, the vehicle swerves left, crossing oncoming traffic and hitting cyclists. It veers over the pavement before entering another road and crashing into a security barrier.
A police officer can be seen jumping another barrier that runs along the side of the road to get away.
Multiple witnesses have said the driver's actions appeared to be "deliberate".
The Metropolitan Police's assistant commissioner, Neil Basu, said the arrested man had not yet been identified and was not co-operating with detectives.
