Police have released footage of a car fleeing the scene after a 14-year-old boy was shot in the head in broad daylight exactly four weeks ago.
The metallic grey 2011 model Range Rover Sport was stolen from a residential street in Balham, south west London, on 23 August.
11 days later it was used to drive to Moore Walk in Newham. A man emerged from the car and shot Corey Junior Davis as he sat talking with friends. A 17- year-old was also shot, but survived.
The CCTV footage from a W19 bus captured the car being driven erratically along Romford Road immediately after the shooting. It heads north towards the A406.
Corey died from his injuries in hospital a short time later.
