A 14-year-old boy has appeared before the ACT Children's Court after allegedly attacking another student with a knife at Lanyon High School in Canberra's south. The incident occurred on Thursday morning, 22 October 2026, and prompted an investigation by ACT Policing. The ACT education minister has also apologised to families because a technical outage delayed the school's communication about the incident.

Police allege that the teenager approached another male student on school grounds at approximately 10:20am and punched him in the head several times. He allegedly produced a knife measuring between 20 and 30 centimetres, threatened the other student and lunged towards him, stabbing him in the hand.

According to police, the injured student ran away, and the knife was allegedly thrown towards his head as he fled. The injured boy was taken to hospital for treatment. Police said the alleged attacker left the scene before presenting himself at City Police Station at about 9pm that evening, where he was arrested.

The teenager appeared in the ACT Children's Court on Friday, 23 October. He faces several charges, including intentionally wounding, assault occasioning actual bodily harm and possessing an offensive weapon with intent. Police also listed a charge of assaulting a frontline worker. He did not apply for bail at the first appearance, and the court heard that a bail application would be made the following Tuesday. The matter is due to return to court next month. The allegations have not been finally determined by a court.

The incident also raised questions about how quickly families were informed. ACT Education Minister Rachel Stephen-Smith apologised for the delay, explaining that the school's administration and messaging systems had been temporarily taken offline while authorities responded to a cybersecurity vulnerability affecting websites around the world.

The vulnerability involved PHP, a programming language widely used to operate websites and online systems. The government said the precautionary response meant the system normally used to send messages to parents was unavailable for a period. As a result, the school community did not receive the usual notification as quickly as it would have under normal circumstances.

Stephen-Smith said the message was eventually sent and that an email was distributed to all families before 3pm on Thursday. During the delay, some students independently contacted their families and arranged to be collected from school.

The minister expressed regret that the delay may have caused additional distress to parents and acknowledged the seriousness of the incident. She said support was being made available to students and staff, and emphasised that schools should be safe places for everyone.

The episode illustrates the challenge of maintaining reliable emergency communication while government agencies respond to cybersecurity threats. Taking systems offline can be necessary to reduce digital risks, but schools also need alternative ways to notify families when an urgent safety incident occurs.

The incident has drawn attention to both school safety procedures and the importance of backup communication arrangements. While the police investigation and court process will determine the legal outcome of the alleged attack, the ACT government may also face questions about how schools can keep families informed during future technology outages.
