Five students were stabbed Tuesday in the boys' locker room of Mountain View High School, which is located in the small city of Orem, Utah.
The suspect, a 16-year-old student with excellent grades and no record, was taken into custody shortly after he stabbed himself in the neck and staff at the school cornered him.
An officer working at the school was able to subdue the student using a Taser, according to Orem Police Chief Gary Giles.
Giles added that the suspect used a knife with a 3-inch blade in the attack.
The incident started around 8 a.m. as students were getting ready for their physical education class.
All of the victims were stabbed at least once and officials said most were being treated for neck and torso injuries. Their conditions ranged from critical to fair, but it is unclear which student suffered the worst injuries.
Junior Karen Martinez told reporters she saw three of the victims running into the school's office.
Other students said the locker room where the stabbing happened was covered in blood.
Police have not released the names of the suspect or the victims due to their ages.
