Edmonton police were called to Lillian Osborne High School on Leger Road Wednesday morning after two male students were stabbed.
The school's principal Janet Hancock confirms two students were hurt, but their injuries do not appear to be serious. Police say the two students were trying to help a female student who was being assaulted when they were injured.
The principal says the suspects are not from the school.
"Having something happen like this is absolutely shocking to me," said Hancock.
Investigators have not released information on the suspects involved, except that there were two males and two females.
Only a few students were in the school at the time as exams are underway.
In a letter posted on the school's website, Hancock states one student was stabbed in the leg and one in the hand. Both were transported to hospital.
Hancock reassures parents that school staff acted quickly during the emergency.
"I need you to know that we had teachers who were in the parking lot at the time of the incident and within seconds 911 was called and first aid was administered. Our staff continues to be an outstanding team. Although this was a disturbing incident to all of us because of the quick response of our team, what could have been a very serious situation was averted."
This incident comes just one week after a stabbing at Archbishop O'Leary High School where students were stabbed during an after-school brawl. In that case, school officials said the students were trying to stop the fight when they were injured.
Edmonton police insist this type of violence is not a trend.
"Knife-related incidents at schools are not prevalent, they're not on the rise," said Edmonton police spokesperson Patricia Thenu.
Lillian Osborne High School is one of Edmonton newest schools in the southwest. It opened in the fall of 2009.
