A Bethlehem High School student and a Canadian teen have been arrested for making school threats that terrified students last September.

Police have made two more arrests in the “swatting” incidents at Bethlehem Central School District – including a 15-year-old student at the high school. The district was hit with a series of threats called into the school last October.

A Long Island teen was arrested Tuesday after police said she posted a threat of mass harm against her high school on Snapchat.
