ALT Detective Chief Superintendent Luke Williams, who leads on policing in north west London, including Barnet, said: "We know that this incident will cause significant concerns in the local community and residents can expect a continued police presence throughout the night. "Detectives are working quickly to establish the circumstances and I would urge anyone with information to get in touch with us. “We are aware of videos circulating on social media, appearing to show the collision and those involved. We would discourage the public from sharing both due to the graphic nature of the footage and to protect the integrity of the investigation."
