Double murders were revenge for 'humiliating' video of teenager being attacked in Milton Keynes woodland

And one of the attackers was murder victim 17-year-old Dom Ansah, the jury heard.

The woodland attack on the teenager, who was also 17, took place in September 2017 and was filmed and widely circulated on social media by the murder victims, the court was told.

The jury at Luton Crown Court heard the video was one of two incidents that served as a “catalyst” for the quadruple stabbing, said prosecutor Ms Newell.

Ms Newell said: “This (the attack) had been videoed which was widely shared on social media and the footage was present on Dom Ansah’s handset downloaded after his death."

She added: “Plainly the incident and the wide sharing of it would have been humiliating and the Crown suggest that in addition to the generalised animosity between the gangs this was a personal grudge held by the boy.”

The other boy, aged 16 years, was stabbed in the buttocks, in another incident which was linked to the events.

Ms Newell said: “The Crown suggests therefore that the defendants had themselves a motive for the attacks at Archford Croft or knew of the bad blood such that, when the time came, they were willing to act upon it in the knowledge that action would involve serious violence,” Ms Newell said.

Drill rap music videos posted on YouTube were used as evidence of the defendant’s affiliation with the B3 gang, which was taken from the Bletchley postcode of MK3.

The jury was to be shown music videos filmed the B3 gang and the M4 Westcroft gang which were said to show threats and animosity between them and involved both the defendants and the two murdered boys.

Ms Newell said: “Evidence of ties to one or the other of those gangs and awareness of the hostility between them include videos uploaded to YouTube on November 19 2018 entitled “#B3w C.Crashit – Why’d we lie (music video)” featuring, the Crown suggests, Clayton Barker, and the two anonymous boys and another video, an M4 production, also uploaded to YouTube on April 7 2019 entitled “#M4 Paperboylez – Viol£nce (official video) and featuring Dom Ansah and Ben Gillham-Rice."

“The lyrics are in urban slang and a glossary of terms has been provided to assist with interpretation. In short, those featuring in the video proudly reference gangs and gang rivalry and glorify the use of knives to cause serious injury.”

Some of the defendants had bragged to friends about the killing following the attack in both spoken and written conversations which the jury was to see, the court heard.

Finishing her summary of the events, Ms Newell said: “The evidence as to who did what and with what state of mind comes from sources in addition to the eye-witnesses including dash cam and CCTV footage, forensic evidence and admissions made by the defendants either because they believed they were confiding in someone who would not “grass” on them or were recording their events for their own sense of glory and satisfaction in written or spoken word.”

The hearing continues.
