A 15-year-old Melbourne schoolboy has undergone emergency surgery after being seriously injured in a machete attack near his school in Cranbourne North.

The Alkira Secondary College student suffered wounds to his neck, back, arms and hands after he was allegedly chased and attacked by three males at Sabel Reserve Playground on Monday afternoon.

Victoria Police said the incident occurred at about 3.20pm, shortly after the teenager had left school with two friends.

Detectives believe three males began calling out to the group and taunting them before pursuing the 15-year-old into the park while armed with machetes.

Detective Inspector Mark Patrick described the alleged attack as an exceptionally violent confrontation intended to frighten the victim before he was assaulted.

“It was similar to a war cry when you go into battle to create fear in their intended victims,” he said.

“It was an extremely violent attack. They started chasing him to Sabel Park, lashing out with their weapons, causing serious injuries to that young man.”

Emergency services were called to the scene and the teenager was taken to hospital, where he underwent urgent surgery for injuries across several parts of his upper body.

Police have not disclosed the hospital where he is being treated because of concerns for his safety.

The boy was not known to police, investigators said, and no motive for the attack has been publicly established.

Detectives are now searching for three suspects believed to be aged between 16 and 20.

Police described the males as being of Middle Eastern appearance and said they were wearing dark clothing and hooded jumpers at the time of the incident.

No arrests have been announced.

The circumstances surrounding the confrontation remain under investigation, including whether the teenager was specifically targeted or had any previous contact with the attackers.

Police are expected to examine security camera footage from homes, businesses and public areas around the reserve as they attempt to trace the movements of the suspects before and after the assault.

Investigators may also seek footage from vehicles travelling through Cranbourne North around the time of the attack.

Anyone who witnessed suspicious behaviour near Sabel Reserve, Alkira Secondary College or surrounding streets on Monday afternoon has been urged to come forward.

Dashcam, mobile phone or security footage could help detectives identify the three males or determine how they entered and left the area.

The location and timing of the attack have heightened concern because it occurred near a school and during the busy period when students were travelling home.

Sabel Reserve sits within a residential area close to the school, making it likely that pedestrians, motorists or nearby residents may have seen part of the incident or noticed the suspects.

Although the victim was accompanied by two friends when the confrontation began, police have not reported that either friend suffered serious physical injuries.

The teenager appears to have been the main target of the pursuit, but investigators have not yet explained why he was singled out.

The decision to withhold details about his hospital reflects the seriousness of the safety concerns surrounding the case.

Police investigations following violent attacks can involve forensic examination of the scene, analysis of video footage, witness interviews and searches for weapons or clothing believed to have been used during the offence.

Detectives will also attempt to establish whether anyone helped the suspects leave the area or conceal evidence after the attack.

The incident comes after Victoria introduced a statewide ban on machetes in response to mounting concern about their use in violent offending.

Since 1 September 2025, machetes have been classified as prohibited weapons in Victoria. It is illegal to own, use, carry, transport, buy or sell one without an exemption or valid approval.

Unauthorised possession can result in a prison sentence of up to two years or a fine exceeding $48,000. Victoria Police advises that exemptions are limited to approved occupational, agricultural, cultural or other lawful circumstances.

The prohibition was intended to reduce access to weapons capable of causing catastrophic injuries, particularly during confrontations in public places.

However, the law does not remove machetes that were obtained illegally, retained after the ban or transferred through unlawful channels.

Police have continued to warn that carrying a weapon for protection can escalate confrontations and expose the person carrying it to serious criminal charges.

The injuries suffered by the Cranbourne North student illustrate the potentially devastating consequences of attacks involving large blades.

Wounds to the neck can be life-threatening because of the major blood vessels, nerves and airway structures concentrated in the area. Injuries to the arms and hands may also occur when a victim attempts to protect the head or upper body.

Even after emergency surgery, victims of serious edged-weapon attacks can face lengthy rehabilitation, reduced movement, nerve damage, scarring and psychological trauma.

Families and friends may also experience significant distress, particularly when an attack occurs unexpectedly near a place normally associated with school and community activity.

The case is likely to renew discussion about safety around schools, public parks and transport routes used by students during afternoon dismissal periods.

Schools can supervise students on campus, but their ability to control behaviour becomes limited once students leave school grounds and enter surrounding public spaces.

Responses to violence near schools may therefore require co-operation between police, education authorities, councils, families and local community organisations.

Measures can include improved lighting, security cameras, visible patrols, safer walking routes and clearer systems for students to report threats before they develop into physical violence.

Authorities also encourage young people to avoid confronting anyone carrying a weapon and to move towards a populated or secure location whenever it is safe to do so.

In an immediate emergency, members of the public should call Triple Zero rather than attempting to physically intervene.

Witnesses can still assist without approaching armed offenders by observing details such as clothing, direction of travel, vehicles, distinguishing features and the location where weapons may have been discarded.

Police have not indicated that there is an ongoing general threat to students or residents in Cranbourne North. Nevertheless, three suspects remain outstanding and the investigation is active.

Residents may notice an increased police presence while detectives gather evidence and attempt to locate those responsible.

Members of the public have also been cautioned against spreading unverified names, photographs or claims about potential suspects on social media.

Incorrect accusations can place innocent people at risk and may interfere with police efforts to obtain reliable evidence.

Information should instead be provided directly to investigators or Crime Stoppers, where reports can be made confidentially.

The immediate priority remains the recovery and safety of the injured teenager.

Police are continuing their search for the three males and have appealed for anyone with information, CCTV or dashcam footage from the Cranbourne North area around 3.20pm on Monday to contact Crime Stoppers on 1800 333 000 or submit a confidential report online.
