A 16-year-old boy required surgery after being slashed with a knife during a house party on Oriel Road that spiralled out of control when gatecrashers arrived on Friday night.
What began as a private end-of-year celebration quickly descended into chaos after the event was advertised on social media, attracting around 80 to 100 uninvited guests to the Clayfield property.
The hosts attempted to shut down the party, pushing hundreds of young people onto the street. During the commotion, the teenage boy sustained a 20-centimetre wound to his lower back.
Chief Inspector Karl Hahne described the injury as horrendous, though not life-threatening. The victim underwent surgery on Saturday morning.
Police deployed a specialist blood detection dog on Saturday to search for the weapon, which had not been recovered at the scene. Chief Inspector Hahne said investigators were confident of locating it.
Officers were already aware of the party and responded to reports of teenagers gathering on the street. The incident occurred on the final official day of schoolies celebrations.
Local resident Jarrah Lloyd witnessed the aftermath, describing teenagers blocking the road and forcing cars to turn around. She said the gathering appeared relatively tame aside from alcohol consumption and the crowded streets.
“There was about 50 kids all just in the middle of the road,” Ms Lloyd said. She noted that most teenagers left quietly when police arrived, including several unmarked vehicles.
Another neighbour, Dennis Comino, observed groups of young people clustered across the street, with officers working to disperse the crowd.
One resident reported the street was closed to the public around 11pm. The scene was littered with beer bottles, cans, mixer drinks, vapes and helium canisters.
Police are continuing their investigation into what triggered the altercation and are appealing for anyone with information to come forward.
The incident follows another serious crime in Clayfield earlier this year, when Universal store founder Greg Josephson was allegedly murdered by a teenager at his home in the suburb.
