Det Supt Haskins said that within 59 minutes of the attack on Max and Mason, Snook was in custody.

“He [Snook] was the adult who could have changed the course of this incident.

“He’s the one that could have stopped this from happening.”

He added: “These individuals, as a collective, went after those two boys.

“They armed themselves together, they travelled together, they travelled back from the attack together, and they were intent on causing harm to whoever they came across.”

Hours after the attack, one of the teenagers was caught on CCTV returning to a property in Hartcliffe carrying a McDonald’s meal.

“Chillingly for me, what we do know is they even stopped off at McDonalds after attacking those two boys,” Det Supt Haskins said.

“I think it speaks volumes really. Two beautiful boys lost their lives, and they went to McDonald’s for an early morning breakfast.”
