Police are investigating after a high school student was stabbed in Melbourne's south-east on Monday afternoon.
A 15-year-old boy was found with serious injuries after an altercation between a group of teenagers, Victoria Police said.
Ambulance Victoria said paramedics responded to reports of an incident in Cranbourne North at around 3:20pm, where they treated one patient.
"A teenage boy was transported by road ambulance to hospital with upper body injuries in a serious condition," a spokesperson said.
Police said the group of teenagers fled the scene on foot.
The Department of Education said the injured teenager was a student of Alkira Secondary College but that the assault took place "outside the school and after school hours".
"The college is providing wellbeing support to those involved," a department spokesperson said.
The ABC understands the alleged offender is not an Alkira Secondary College student.
Anyone who witnessed the incident, has dashcam or CCTV footage or information is urged to contact Crime Stoppers.
