Two additional people have been charged in connection with the suspected bashing murder of a Sydney youngster in Doonside.
A week after a bereaved Sydney mother asked for assistance in apprehending the murders of her teenage son, police have arrested two further suspects in connection with the incident.
Jason Galleghan, 16, was found battered in his home in western Sydney on August 4 and later died at Westmead Hospital.
Rachel Galleghan described her son's death last week as "utterly terrible and tragic."
"We have all lost a piece of ourselves that will never be replaced, and I would want to ask for the community's continued support in pursuing Jason's case to ensure that justice is done," she added.
Eight people, ranging in age from 13 to 32, have been charged with their respective roles in the incident and are in custody.
Police released CCTV photos of two males seen in the area of Jason's Doonside home on the afternoon of his alleged murder last week.
Additional charges were filed against two people on Tuesday following a dawn raid at a Kingswood flat on Tuesday, during which police recovered a mobile phone and clothing.
They apprehended and charged an 18-year-old male with hiding a severe indictable offense of murder.
The kid was given stringent conditional bail with an appearance date of November 25 in Blacktown Local Court.
A second search warrant was performed at Bidwill, and a 36-year-old woman was detained and charged with murder, taking or detaining someone in company with the goal of gaining an advantage, and causing real and serious bodily harm.
The woman was denied bail and ordered to appear Wednesday in Mt Druitt Local Court.
