Armed police have arrested a man after a vehicle crashed into a security barrier outside the Palace of Westminster, injuring several pedestrians.
A CROWD of pedestrians has been injured after they were hit by a auto outside the British Houses of Parliament at Westminster in London.
Witnesses told reporters that the man was led away in handcuffs by officers as ambulances and police vans surrounded the scene. A number of pedestrians have been injured.
Armed officers swarmed the scene and cordoned off a large area around the parliament building in central London, usually bustling with tourists and government workers.
Metropolitan Police Assistant Commissioner Neil Basu said there was "no intelligence at this time of further danger" to Londoners following the attack.
Images from Sky News and social media showed a man in a puffy black jacket who was surrounded by police and led away in handcuffs from a silver vehicle.
"It looked deliberate", he said. "There was a loud bang", he said. A video showing police vehicles crowding the auto quickly went viral on Twitter.
"The auto went onto the wrong side of the road to where cyclists were waiting at lights and ploughed into them. I heard some noise and someone screamed", she said.
None of the injuries were life-threatening, police said.
A vehicle that crashed outside the Houses of Parliament is surrounded by members of the emergency services in Westminster, London, Britain, August 14, 2018.
Eyewitnesses described the auto as being driven at high speed before hitting carriers.
Police patrols were today stepped up across Britain after a auto collided with cyclists and pedestrians before crashing into security barriers in Westminster.
Added security was installed outside of Parliament a year ago after a man mowed down pedestrians in Westminster, killing four, and then stabbed a police officer to death.
Prime Minister Theresa May said her thoughts were with the injured and thanked the emergency services for their "immediate and courageous" response.
Four pedestrians and a police officer were killed.
Footage shot outside Parliament showed cyclists helping at least one biker laying on the ground as the LAS and armed officers arrived on the scene.
Last year Khalid Masood murdered five people, including a police officer and injured 50, when he ploughed his auto into pedestrians in a terrorist attack.
Westminster station has been closed for both entry and exit due to the security alert, Transport for London said. On that occasion, Khalid Masood drove a vehicle into a crowd, killing four people.
