A 15-year-old boy was arrested on Wednesday (Oct. 7) after making online threats to bring a gun to school and "kill all the girls" at his Idaho high school because none of the school's cheerleaders would send him nude photos.

Highland High School in Pocatello, Idaho was under lockdown throughout the day after a post on Facebook featuring a text conversation between the boy and friend was reported to district officials, the Idaho State Journal reports.

Local news station KIDK-TV posted screenshots of the conversation where the student allegedly told a friend that he would bring two guns and hunting knives to school on Friday morning and "kill all the girls."

The screenshots show the student's friend was alarmed by the threats.

"Over freaking nudes? Dude," he wrote. "We're kids. Nothing valuable except our lives so leave us alone."

The Idaho State Journal also reports that the student used his Twitter account to post threatening and harassing messages to other Highland High School students -- mostly girls.

The student was arrested Wednesday night and charged with one count of threatening violence at a school and another count of telephone harassment.
