Overview

• Two 19-year-olds were ambushed late Wednesday by four people dressed in black and wearing balaclavas at the bus interchange opposite Mount Druitt station.
• One victim died from chest stab wounds, and the other sustained a stab that passed through his arm into his chest and was under sedation in hospital.
• A third man believed to be waiting for a bus and unrelated to the groups was also assaulted, police said.
• Investigators described the attack as violent and frenzied and conducted an emu-line search across the interchange, road and railway, which was temporarily closed.
• Police are examining possible ties to western Sydney postcode gangs, including a Doonside-linked group, and are assessing reports of the question “Are you 67?” as a lead while appealing for CCTV and witnesses.
