The man who admitted killing Dylon Barnes following a Seven Kings music event a year ago, has been jailed for 12 years.

Jean Marc Dable, 25, of no fixed address, pleaded guilty to manslaughter at the Old Bailey on Friday, November 6 and was sentenced at the same court on Wednesday, November 11.

Dylon – full name Akeem Dylon Barnes – was fatally stabbed by Dable following a music event in converted garages in Telegraph Mews.

Police were called at 6.10am on November 24, 2019, to reports of a group of people fighting.

They administered first aid until paramedics arrived and Dylon was taken by London Ambulance Service to hospital where he died at 12.36pm.

The court heard Dable and Dylon had attended the event and there had been no issues, but as they left, a disagreement between members of their two groups took place and the situation escalated.

Dylon, 24, attempted to bring calm but despite the best efforts of someone else in the group to restrain Dable, he lunged at Dylon and stabbed him.

Dable was charged with murder.

Following sentencing, Det Insp Adam Callaghan said: “Homicide teams across the Met work relentlessly to achieve justice for victims. This is what motivates us and as always, our team’s thoughts and sympathies remain with Dylon’s family who continue to grieve for their lost son.

“Dable will now be prevented from carrying out violence against any kind and the streets of London are all the safer without him. He will have a number of years to seriously reflect on the decisions he made that night which resulted Dylon’s life coming to such a brutal end.”
