Rooftop footage shows car mowing down cyclists and pedestrians before crashing into Parliament barrier
This is the moment the suspected Westminster terror attack was captured unfolding on a rooftop camera.
A silver Ford Fiesta is seen being driven next to Parliament Square towards Westminster Abbey on Tuesday morning.
But, as a group of cyclists stop at a traffic light, the vehicle fails to come to a halt and ploughs into them.
As an ambulance passes the car on its right-hand side, it swerves left - crossing oncoming traffic and hitting a number of pedestrians as it mounts a pavement.
The car then enters a small road and accelerates to up to 50mph, witnesses said, before 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.
The driver, a man in his late 20s, was surrounded by police before being arrested on suspicion of terror offences.
There was nobody else in the vehicle and no weapons were found, the Metropolitan Police said.
Police said he is being held in custody at a south London police station after armed officers swarmed the scene following the suspected terror attack just before 7.40am.
Two people were taken to hospital, while a third person with minor injuries was assessed at the scene, the London Ambulance Service (LAS) said.
Prime Minister Theresa May said her thoughts were with those injured and thanked the emergency services for their "immediate and courageous" response.
