All victims are being treated for injuries and their condition ranged from critical to fair.
Five students were stabbed inside their Utah high school Tuesday and a 16-year-old boy identified as a suspect was taken into custody, police said.
The stabbings of the male students at about 8 am at Mountain View High School happened near the school's gym in Orem, a city of about 90,000 people about 40 miles south of Salt Lake City, authorities said.
All of the victims were stabbed at least once and were being treated for their injuries at local hospitals. Their conditions ranged from critical to fair, Orem police Lt. Craig Martinez told reporters.
The suspect was apprehended shortly after the stabbings by a police officer regularly assigned to work at the school, Martinez said.
"We do have the suspect in custody and the rest of the students are safe," Martinez said.
The school was put on lockdown after the stabbings for about an hour. Students were later allowed to remain in school or leave for the day.
Dozens of parents arrived at the school to take their children home.
