A man has been arrested after a car hit cyclists and pedestrians and crashed into security barriers outside parliament.

This is what we know so far:

:: The driver of the car, a man in his late 20s, was arrested at the scene by armed officers on suspicion of terrorist offences. He was wearing a black puffer jacket and was led away in handcuffs. He is being held at a south London police station.

:: Police said the suspect was "not currently co-operating", and they had not formally identified him. He does not appear to be known to either MI5 or counter-terrorism policing. According to Sky sources, he is believed to be from the Midlands.

Crash 'appears to be deliberate act'

:: Assistant Commissioner Neil Basu, who leads counter-terrorism policing in the UK, said the incident "appears to be a deliberate act".


:: The Metropolitan Police's counter-terrorism command is leading the investigation. It is being treated as a "terrorist incident".

:: Witnesses said the crash looked deliberate. The car is said to have been driven at speed, and to have lifted off the ground when it hit the barriers.

:: No other suspects at the scene have been identified or reported to police.

:: There is "no intelligence at this time of further danger to Londoners, or the rest of the UK, connected to this incident", Mr Basu said.

:: Two people were taken to hospital, one of whom, a man, has since been discharged. A woman is being treated for serious but non life-threatening injuries at St Mary's Hospital in Paddington. Another man, who was treated at the scene, did not need to go to hospital.

:: Scotland Yard said the car was "in collision with barriers outside the Houses of Parliament" at 7.37am.

:: The Ford Fiesta "collided with a number of cyclists and pedestrians".

:: There was no one else in the vehicle, and officers have not found any weapons so far.

:: At lunchtime, cordons along Victoria Embankment were lifted and Parliament Square and Whitehall reopened. But the immediate area around the incident was still taped off.

:: Witness Ewalina Ochab said: "I think it looked intentional - the car drove at speed and towards the barriers.

"I was walking on the other side [of the road]. I heard some noise and someone screamed. I turned around and I saw a silver car driving very fast close to the railings, maybe even on the pavement."

:: Another witness, Jason Williams, said: "I saw a car going at high speed towards Parliament.

"It hit a bollard. It looked deliberate. It didn't look like an accident. How do you do that by accident? It was a loud bang."
