Members of that group were in conflict with a rival gang known as Representing the Danger (RTD), based around Rochdale and Oldham.
Describing the feud, High Court judge Mr Justice Goose said: “It was played out in social media and through drill rap music, with threats of violence, the display of weapons, including firearms, machetes and crossbows.
“Entering the territory of one gang was treated as provocation, to be met by violence or the threat of violence.”
On the afternoon of 5 November 2020 a member of RTD was attacked by a group – including Soyoye – in Piccadilly Gardens in Manchester city centre.
Jurors heard that evening, at about 18:00 GMT, a large group of RTD members carrying machetes, knives and other weapons descended on Birchenall Street in Moston, seeking revenge.
A group of M40 members including Soyoye – also armed with similar weapons -met the group but were outnumbered.
Soyoye was injured and tried to flee, but became separated from his group and fell to the ground.
Police said he was surrounded by nine men and boys, who repeatedly stabbed and kicked him to death.
Detectives investigating the murder found rap lyrics on a mobile phone seized from the 16-year-old boy which bragged about killing “MD” – a nickname police said was used by Soyoye.
After a first trial for his killers, nine men were also convicted over a plot to attack RTD gang members in revenge for Soyoye’s death.
However one of those men, Ademola Adedeji, had his conviction for conspiracy to inflict GBH quashed on appeal after judges heard he was wrongly identified in a drill rap video related to the gang conflict.
