A number of casualties are being treated at the scene after reports that a vehicle was involved in a collision in north London.
The Metropolitan Police say they are dealing with a “major incident” as a result of the collision in Seven Sisters Road, Finsbury Park.
The incident is described as being close to Finsbury Park station and mosque.
London Ambulance Service say they have sent a “number of resources” to the scene.
At least a dozen police cars have been sent to the area and a helicopter is overhead. Pictures on social media of the scene suggest it occurred at the entrance to Whadcoat Street.
The Met Police said in a statement: “Police were called just after 0020hrs 18 June to reports of a vehicle in collision with pedestrians.
“Officers are on scene with other emergency services.
“There are a number of casualties being worked on at the scene.
“There has been one person arrested. Enquiries continue.”
The force said more information would be provided when it can be confirmed.
Witness Cynthia Vanzella told Sky News she was trying to sleep when she heard a lot of noise outside.
She said: “I saw many people shouting, taking over half of Seven Sisters Road, I thought that something bad has happened.
“I could see at least two people on the floor, not moving. They were doing cardiac massage. It was difficult to watch.”
“There were people sitting on the floor with their head in their hands.
“In a matter of seconds a police car was hear. They were very fast.”
