The court heard that the 20-year-old and his two friends and come across their attackers by chance with no evidence existing to suggest a meeting had been planned or of there being any prior contact between the two groups.
They were then attacked by the six with all three victims receiving significant knife injuries.
Detective Chief Inspector Vanessa Rolfe of the Homicide and Major Enquiry Team, said: “This was an horrific offence in which a 20-year-old male has lost his life following an outbreak of violence in which knives were used.
“Those involved continued to attack Bradley even after he had been wounded and was laid defenceless on the floor. We welcome the sentences imposed on them today for their roles in the joint enterprise murder of a male who, at 20-years old, had his whole life ahead of him.
“The victims did nothing to provoke the horrendous attack on them and officers left no stone unturned to identify and arrest those responsible for this senseless act of violence.
God, I hate it when I’m just going for a stroll in my neighborhood and a fucking outbreak of violence happens.
