The mother of a teenager who was shot dead in Greenwich, south east London, has urged others to help "stamp out" violence on the anniversary of her son's death.
Eighteen-year-old Ethan Nedd-Bruce was found dead outside a house on Armitage Road in October 2018, but police are still hunting for his killer.
They believe that Mr Nedd-Bruce was involved in an altercation with a group of males after he left a nearby chicken shop and are re-appealing for any information about the incident.
The males pursued Mr Nedd-Bruce on a motorbike and in a silver Ford Kuga, before attacking him in Hevelius Close.
Detectives continue to investigate the exact circumstances of the murder, though it is believed it was a targeted attack that was linked to a number of other incidents in the area between two criminal networks.
Mr Nedd-Bruce's mother, Cherie Nedd, said that the lives of her family had been "shattered, never to be repaired".
She added that the attack had had a profound impact on her local community.
A memorial will be held to mark one year since Mr Nedd-Bruce's death featuring tributes to his character. Asked about what she would say to her son's killers, Ms Nedd said:
Officers have returned to the scene of the attack on Armitage Road, and images and footage have been released as the search continues.
One image shows a white male with a beard holding a mobile phone, who police believe could be a key witness. He walked past the chicken shop moments before the attack.
The footage shows the two vehicles that were used by Mr Nedd-Bruce's attackers during the incident.
It shows a motorbike with a rider and pillion passenger and a silver Ford Kuga with a number of occupants.
On the night of the attack officers were called to the estate in Greenwich at 9.25pm following reports of a disturbance, where they found Mr Nedd-Bruce collapsed.
Police initially believed that he had suffered a stabbing injury, but a post mortem later revealed that it was caused by a gunshot.
