About 4.20pm (Monday 24 November 2025), emergency services were called to Bruce Purser Reserve on Caballo Street following reports of a stabbing.
Officers attached to The Hills Police Area Command arrived to find a 17-year-old boy with a stab wound to his leg.
He was treated by NSW Ambulance paramedics; however, he died at the scene.
Police established a crime scene, and detectives from The Hills – with assistance from State Crime Command's Homicide Squad – commenced an investigation under Strike Force Crawton into the incident.
As part of the investigation, strike force detectives charged a 15-year-old boy over his alleged role in the fatal stabbing. He remains before the court.
Following further investigations, strike force detectives – with assistance from officers attached to the Public Order and Riot Squad – executed a search warrant at a home on Collins Circuit, Rouse Hill, about 9.45pm yesterday (Tuesday 25 November 2025).
During the search police arrested a second 15-year-old boy before taking him to Castle Hill Police Station where he was charged with murder.
