Popoola and his co-defendant, Tayvon Etefia, were convicted at the Old Bailey in connection with Harker’s death in June 2025 in Enfield, north London.
Prosecutors told the court that the incident was linked to an ongoing feud between two rival groups, which intensified after comments were exchanged on Snapchat. The court heard that Popoola and Etefia allegedly chased Harker on an electric bike before Popoola shot him at close range.
Following the incident, the pair reportedly abandoned the bike, discarded their clothing and attempted to flee. Etefia was arrested shortly before boarding a train to France, while Popoola was later arrested in Paris and extradited to the UK.
The jury also found three other individuals guilty of attempting to assist the suspects in evading justice.
Popoola and Etefia are expected to be sentenced later this week.
