A 17-year-old Amityville High School student has been accused of threatening to blow up the school with a bomb.
School officials called Amityville village police after finding the written note in a stairwell shortly before 9 a.m. Monday, authorities said.
Suffolk County police First Squad detectives investigated and learned the identity of the girl, who is from North Amityville. Authorities did not release her identity.
She was arrested and charged with falsely reporting an incident, a felony. She will be arraigned Tuesday at First District Court in Central Islip.
