About 9.50pm on Thursday 23 February 2023, emergency services were called to Leonard Reserve, Roselands, following reports of a brawl.
Officers attached to Campsie Police Area Command arrived and found a 24-year-old man suffering stab wounds.
He was treated by NSW Ambulance paramedics; however, died at the scene.
The man has since been formally identified as Ghassan Long.
Campsie detectives - assisted by the State Crime Command's Homicide Squad – established Strike Force Poton to investigate the circumstances surrounding the Ghassan's death.
Following inquiries, police charged a 21-year-old man with affray and concealing a serious indictable offence, a 20-year-old man with affray, conceal serious indictable offence and hindering an investigation and a 22-year-old man with affray.
