A man has been arrested on suspicion of terrorism offences after a car crashed outside the Houses of Parliament. The vehicle swerved into cyclists and pedestrians shortly after 07:30 BST, injuring three people. The suspect, in his late 20s, is not believed to be known to MI5 or counter-terrorism police, and is not co-operating with officers. One woman is being treated in hospital for serious but non life-threatening injuries. Scotland Yard's head of counter terrorism Neil Basu said 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 and the vehicle is being searched. No-one else was in the car and no weapons have been found. The government's Cobra emergency committee is meeting later. A number of eyewitnesses have said the silver Ford Fiesta, which was travelling westbound, 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 drives over a pedestrian crossing before crashing into the security barriers. A police officer can be seen jumping over another barrier to get out of the way. Parliament is currently not sitting. Westminster tube station is closed and streets around Millbank, Parliament Square and Victoria Tower Gardens have been cordoned off. Nearby Strutton Ground has also been closed to the public. People were moved further back from the area twice as police put up a Terrorism Act cordon. Images posted to social media showed a man in handcuffs being led away from the car by officers after the crash. A London Ambulance Service spokesman said two people had been taken to hospital with "injuries that are not believed to be serious", and a third patient with minor injuries had been assessed at the scene. One of those taken to hospital, a man, has since been discharged. #parliament #westminter #london
