A teenager has been rushed to hospital after being hit by a marked police car on an emergency call, police said.
The car struck the 18-year-old pedestrian in Clapham Road near Clapham Common, south-west London, at about 3.40pm on Friday, Scotland Yard said in a statement.
Witnesses said the Metropolitan Police officers were responding to a fight, according to the Independent.
The teenager was taken to a nearby hospital and officers are awaiting an update on his condition.
Road closures were in place as police and London Ambulance Service attended the scene following the incident.
Isabelle, the victim’s friend, told the newspaper: “He ran over... He was coming across the road to say hi to me.”
Another witness said there had been a "big fight" on the pavement of Clapham Road at the time.
A Met Police spokeswoman said the car was travelling with its blue lights on while responding to an emergency call not believed to be related in any way to the pedestrian.
The crash was beside a pedestrian refuge island near Lambeth College.
The Met's Directorate of Professional Standards has been informed.
Scotland Yard said: "Officers in a marked police vehicle were involved in a collision with a pedestrian in Lambeth.
"The 18-year-old pedestrian has been taken to a south London hospital. We await an update on his condition."
The London Ambulance Service said a man was treated at the scene before being taken to hospital "as a priority".
