A 17-year-old boy died after being stabbed in Blacktown on September 1, following a brawl.
NSW Ambulance paramedics attended and treated seven people at the scene for stab wounds, while police established a crime scene and seized several items, including a ‘Zombie’ knife, machete, kitchen knives and golf clubs.
With investigations ongoing, police released CCTV vision of a man who may have boarded Blacktown Train Station and left the train at Chester Hill Train Station following the incident.
The man depicted in the CCTV is aged in his early 20s, of medium, solid build, about 165cm-180cm tall with a shaved head.
He is depicted wearing a black, hooded jacket, black tracksuit pants, black and white running shoes and a black face mask.
Blacktown Police Area Commander, Superintendent Steve Egginton, said detectives are following a number of lines of inquiry and are keen to speak to the man depicted in the footage.
“Strike Force Delrine detectives are determined to reach a resolution in this matter and believe there were other people involved in the boy’s death,” Mr Egginton said.
“The boy’s family and loved ones deserve answers and detectives will continue to investigate this matter until all those involved are brought before the courts.
“We are urging the community to look closely at the CCTV footage and to come forward if they have any information about the identity of the person depicted in the vision.”
Four people – three 17-year-old boys and a 20-year-old man – have been charged over their alleged roles in the incident.
A fourth 17-year-old boy was also charged with breach of bail.
They remain before the courts.
