A £20,000 reward has been issued for information leading to the killers of a teenager who was gunned down at a music festival. 

Alex Ajanaku was murdered on the Beaumont Estate, in Leyton, in the early hours of September 1 2021.

The 18-year-old was attending an illegal rave at about 11.50pm where only a small group remained.

Shots were heard and then a moped rider with pillion passenger rode through the event dispersing the crowd.

Police launched a murder investigation after being called at around 1.25am that night.

Officers have released images of 20 people that officers want to speak to as witnesses who were on the estate that night who may hold vital information.

They are renewing its appeal with a £20,000 reward if any arrests lead to a conviction.

Scotland Yard said the vehicle that is believed to have been used to commit the murder was a black Kia Sportage.

It had been stolen from Chingford shortly before midnight on August 16 2021.

On September 3 2021, it was found abandoned and fire damaged in Walthamstow.

Detective Sergeant Fenton Davis, from the Specialist Crime Command, recently appeared on Crimewatch Live to appeal for witnesses.

“Although we have made four arrests as part of our investigation, we still need your help to identify who was responsible for taking Alex’s life," he said.

“Alex was at a music event on the estate the previous evening and a large number of people would have been there.

"At about 11.50pm on the 31 August 2021 there was an incident on the estate when a moped rider with pillion passenger rode through the event and it caused the crowd to disperse.

Did you see this incident? Whilst we do not believe the incident with the moped was the catalyst for Alex’s murder, we want to build up as detailed a picture as possible as to what occurred on the estate that night. Any piece of information could be crucial to the investigation.

“Please do the right thing and call us. A reward of up to £20,000 is on offer for information leading to the identification, arrest and prosecution of those responsible for Alex’s murder.”

In a previous appeal Alex’s mum said: “My life was completely devastated by Alex’s murder. I loved him so much and miss him every day.

“I want to appeal to anyone who has any information about what happened or who is responsible for Alex’s death to come forward and talk to police.”
