A woman in her 80s has been left with potentially life-threatening injuries after a crash with a bus in Oxford Circus.
Emergency services rushed to the scene at 3.30pm on Monday after receiving reports of a crash involving a pedestrian and a bus at the junction of Oxford Street and Regent Street.
Metropolitan Police said a woman in her 80s was taken to hospital with "potentially life-threatening" injuries.
Initial reports on social media suggested the person hit by the bus was a cyclist, however Scotland Yard has confirmed it was a pedestrian.
A London Ambulance spokesperson told the Evening Standard: "We sent a number of crews to the scene including an incident response officer, paramedic team manager and ambulance crew.
"We treated a woman at the scene for leg injuries and took her to a major trauma centre."
Road closures were in place but police officers from the Westminster twitter account said enquiries at the junction have now concluded and the road has reopened.
No arrests have been made and enquiries are ongoing. An air ambulance was also sent to the scene.
