Alex Ajanaku was 18 years old when he was killed on the Beaumont Estate in Leyton at around 1.25am on September 1, 2021.

The majority of people had left the area by the time of the incident but a small group remained sitting on a bench when shots were fired, police said.

It is believed a black Kia Sportage was used during the killing.

The Met said it had been stolen from Chingford shortly before midnight on August 16.

The vehicle was later found abandoned and fire damaged in Walthamstow on September 3.

A 43-year-old man was arrested on September 2 on suspicion of murder.

He was released on bail and, following police enquiries, was released with no further action to be taken against him.

Det Sgt Fenton Davis, of the Met’s Specialist Crime Command, said: "We remain as committed as ever to getting justice for Alex and his family.

"I hope with the passage of time, witnesses may now feel able to come forward.

"At the time, I said there are people out there with information and I believe that is still true.

"A year and a half is a long time to carry around information about the death of a young man with his whole life ahead of him, please do the right thing and tell us what you know.

"Alex’s family deserve to know the truth. You do not have to speak directly to police, you can share what you know anonymously with independent charity Crimestoppers.”
