Five students stabbed in boys' locker room at Utah high school

Five students have been stabbed at a school in Utah.

Police said the victims were attacked in the boys' locker room at the Mountain View High School.

A 16-year-old boy - who stabbed himself in the neck before he was subdued with a Taser by an officer working at the school - has been arrested.

The teenager, who has not been named, is believed to be a straight-A student with no record of disciplinary problems.

All the victims were stabbed at least once and are being treated for neck and torso injuries, police chief Gary Giles said.

Their conditions ranged from critical to fair. The suspect was also taken to hospital.

School district spokeswoman Kimberly Bird said the attacker was a new student at the high school who had previously been homeschooled.

Student Paxton Ransom said he saw blood on the floor of the locker room and thought it was fake until he saw someone on the ground who had been stabbed.

He told how he ran away and hid with other students in the school's weight room until the suspect was apprehended.
