Police are searching three addresses in the Midlands after a man was arrested on suspicion of terrorism following a car crash outside Parliament.

The 29-year-old British suspect is not believed to be known to MI5 or counter-terrorism police.

A vehicle swerved into cyclists and pedestrians shortly after 07:30 BST before crashing into a barrier outside the Houses of Parliament.

Two people were treated in hospital but were later discharged.

A third person with minor injuries was assessed at the scene.

No-one else was in the car when it crashed and no weapons were found in it.

Searches took place at two addresses in Birmingham and a residential property in the Radford and Arboretum area of Nottingham.

A woman who witnessed police arriving to search the Nottingham property told the BBC the raid took place between about 15:00 and 16:00 BST. She said other officers in plain clothes remained at the scene for a few hours.

Sham Khatun said: "A van parked up outside the house, they broke into the house. They shouted 'Police!', they broke a couple of doors."

Scotland Yard's head of counter terrorism Neil Basu said: "Given that this appears to be a deliberate act, the method and this being an iconic site, we are treating it as a terrorist incident."

The assistant commissioner added there was "no intelligence at this time of further danger" to London or the UK as a whole.

The suspect, who has not been formally identified, is being held at a south London police station but police said he was not co-operating with officers.

Security minister Ben Wallace said he was British but originally from another country.

Labour's Roger Godsiff, MP for Birmingham Hall Green, tweeted that the driver was "believed to have been living in my constituency".

Home Secretary Sajid Javid said: "The briefing I have received from counter-terrorism police and the security services is that work is ongoing and they are doing everything they can to find out more about the incident.

"We must keep an open mind about what has happened."

Only the area around the scene of the crash remains sealed off

Cyclists were seen on the ground after the crash

Police say the vehicle was driven from Birmingham to London on Monday night, was in the Tottenham Court Road area until about 06:00 and was seen driving around Westminster and Whitehall for 90 minutes before the incident.

A number of eyewitnesses have said the silver Ford Fiesta, which was travelling westbound in Parliament Square, appeared to deliberately hit members of the public as it swerved into the opposite lane.

Footage released by the BBC shows the moment when the car then crosses over a traffic island in the middle of the road before crashing into the security barriers. A police officer can be seen jumping over another barrier to get out of the way.

Westminster Tube station was closed and streets around Millbank and Parliament Square cordoned off for several hours.

The immediate area around the incident remains taped off and screened by white temporary fencing. Parliament is not currently sitting.

British Transport Police said it was increasing patrols in England, Scotland and Wales and that its officers would be "highly visible on trains and at stations".

The prime minister paid tribute to the "formidable courage" and professionalism of the emergency services who "ran towards a dangerous situation in order to protect the public".

Urging the public to remain vigilant but "carry on as normal", Theresa May added: "For the second time in as many years the home of our democracy, which is a potent symbol of our precious values of tolerance and freedom, has witnessed terrible scenes just yards from its door."

The Houses of Parliament are surrounded with security barriers of steel and concrete. The measures were extended in the wake of the Westminster Bridge attack in March 2017 when Khalid Masood ploughed a car into crowds on Westminster Bridge, killing four people.

Security arrangements at Parliament have progressively tightened since 2001. In the aftermath of the 7/7 attacks, new truck bomb-proof barriers were installed in an effort to "target harden" Westminster.

These include the reinforced low black rampart-like walls that surround Parliament itself and a highly visible armed police presence.

Visitors need to go through a chicane-like system designed to help armed officers spot suspects. The one significant weak spot was the main vehicle gates - as became apparent in March 2017's one-man attack.

That triggered an internal security review that has led to changes that remain secret - although it's apparent to Londoners that there are now more armed police than ever before patrolling the area.

The threat of terrorism is a constant concern for Parliamentarians - it's not new. Irish republican paramilitaries murdered Airey Neave MP in 1979 in a car bomb that exploded within the palace grounds. And the dilemma remains the same: how best to balance security with guaranteeing that the heart of British democracy remains open to the people.

The prime minister's official spokesman said as of the end June 2018 there were 676 live investigations into potential terrorist plots.

He said since March 2017, 13 Islamist plots and four far-right plots had been foiled.

Scotland Yard is asking anyone with information on Tuesday's crash to call 0800 789 321. Anyone with video or pictures of the crash is asked to send them to police.
