On Thursday, October 13, 2022, Cassius Turvey was walking home from school with a group of friends in Perth.
A black Ford Ranger ute stopped beside them at about 4.30pm, and passengers emerged allegedly shouting racial slurs and the word "run."
It is alleged a 21-year-old among them caught up to Cassius and attacked him with a metal pole.
Rushed to hospital with serious head injuries, he was quickly transferred to the Perth Children's hospital with two brain bleeds.
He was discharged after five days, but back in hospital within hours after suffering seizures and two strokes.
Cassius was placed in an induced coma, and died on Sunday, October 23. He was 15.
Jack Brearley was charged with his murder, and has now been charged with aggravated assault occasioning bodily harm, allegedly toward a 13-year-old boy who was present when Cassius was allegedly attacked.
Bearley has also been charged with stealing the boy's crutches.
Police haven't ruled out further arrests against other possible attackers. They believe four people were inside the ute at the time.
WA Police Commissioner Col Blanch said it was "a significant investigation with multiple witnesses".
"The police must get this right," Commissioner Blanch said.
"We have spoken to all witnesses present... the investigation is ongoing.
"There may be further charges, but we do have a lot of evidence to be going through."
Cassius' family say he was attacked because he and his friends were presumed responsible for breaking windows in the neighbourhood.
