An 18-year-old man was taken to hospital after being shot near a girls' grammar school.
An investigation to trace the gunman was under way, police said, confirming that the teenager had received a single gunshot wound.
He was taken by ambulance to the William Harvey Hospital at 8pm on Monday following the shooting in Frith Road, Dover, Kent, where the Dover Grammar School for Girls is located.
A Kent Police spokesman said: "Police are currently dealing with an incident in the Frith Road area of Dover following reports of a shooting which took place just after 8pm, where a man has received a single gunshot injury. The man has been taken to hospital where he is currently in a stable condition.
"Police are currently at the scene and there are a number of road closures in place around Frith Road, Charlton Green and Salisbury Road."
