Two more people have been charged with the murder of a 14-year-old boy who was chased and stabbed to death, West Midlands Police said.
The force said a post-mortem examination confirmed Dea-John died from a stab wound to the chest.
A 14-year-old boy from Wolverhampton and a 16-year-old boy from Great Barr will appear before Birmingham Magistrates’ Court on Monday.
It brings the number of people charged in connection with Dea-John’s death to five.
Michael Shields, 35, appeared at Birmingham Crown Court on Friday charged with the youngster’s murder.
Mr Shields, from Alvis Walk in Castle Bromwich, will appear at the same court for a plea hearing on August 5 and a provisional trial date has been set for February 28 next year.
Two other suspects, 38-year-old George Khan, from Newstead Road, Birmingham, and a 14-year-old youth, who cannot be named for legal reasons, appeared at the city’s magistrates’ court on Friday.
They were remanded into custody until Tuesday where they will appear at Birmingham Crown Court.
The force said it was investigating racist language directed at Dea-John and his friends before the incident, and has referred the case to the Independent Office for Police Conduct over previous incidents involving the victim.
A police statement added that detectives are continuing to “work diligently” on the case and had made the arrests after “acting on information”.
The statement continued: “It comes as the family of Dea-John have appealed for calm in our communities following his tragic death. It follows social media rumours encouraging trouble in retribution for the teenager’s murder this weekend.”
Dea-John’s family previously paid tribute to the “incredibly talented” teenager and called for an end to knife crime, saying: “How many more mothers will have to mourn for their sons for this to stop?”
“This loss not only affects us but everyone Dea-John knew, we have lost a son, his siblings have lost a brother and others have lost a friend.
“The passing of this incredibly talented young boy will be felt by us all.”
