Five students were stabbed inside a Utah high school boys' locker room on Tuesday before the 16-year-old male suspect turned the weapon on himself, school officials said.
The incident at Mountain View High School in Orem, Utah, occurred just before 8 a.m. MT (1500 GMT), and prompted a brief lockdown of the school, the Alpine School District said in a statement.
The stabbing suspect was apprehended by a school resource officer before he and the victims were transported to local hospitals, the school district said.
Their injuries range from minor to critical, it added.
Police did not release additional details about the circumstances surrounding the attack or what might have motivated it.
Students will be released to their parents later in the morning, police said.
