A Long Island high school student has been arrested after he allegedly posted on a social network that there would be a shooting and bombing at his school, according to Suffolk County police.
The teen was charged with making a terroristic threat after the alleged threats against Mount Sinai High School were posted on the social media app Yik Yak.
Several parents and students read the post -- which said the shooting and bombing would happen on Tuesday -- and called school authorities, police say.
The student, of Mount Sinai, will appear in family court on Tuesday.
Suffolk County police say that school resource officers will be at the school Tuesday.
