Police were called at around 20:40hrs on Thursday, 26 May to reports of males having fired shots at a car in Armitage Road, SE10.
Officers, including armed officers, attended and found evidence of a discharge of a firearm.
A 28-year-old man was subsequently found in nearby Felltram Way, SE7 suffering a gunshot wound.
He was taken to hospital by the London Ambulance Service where he remains in a serious but stable condition. His injuries are described as non life threatening.
