Two people were injured when a car drove into security barriers outside the British parliament on Tuesday and the driver was arrested, emergency services said, with counter-terrorism police leading the investigation into the incident.
Neither of those hurt were believed to have suffered serious injuries and police said they were trying to piece together what had happened.
“While we are keeping an open mind, the Met’s Counter-Terrorism Command is leading the investigation into the #Westminster incident,” London’s Metropolitan Police said on Twitter.
Earlier, police said the male driver of the car had been arrested at the scene of the crash which occurred at 0637 GMT.
Witness Jason Williams said the car had struck a barrier on a lane used for access to the parliament building with force. He said he thought it was deliberate car accident lawyer.
“It’s a very serious incident,” he told reporters. “There was smoke coming from the vehicle.”
Images shot by a Euronews journalist showed police pointing their guns at a vehicle. Footage on social media showed a handcuffed man being led away by heavily armed police. Other footage showed a cyclist lying on the street.
“I saw the cyclists, injured cyclists. I’ve seen people, about 10, on the road, lying down, but I haven’t seen any fatalities,” Williams said.
London’s Ambulance Service said it had treated two people for injuries at the scene and they had been taken to hospital. Their injuries were not believed to be serious.
