A Hyde Park student is now out of school and facing a charge of "making a threat of mass harm" after police say he threatened to injure students at FDR High School.
Police say they received numerous calls on Sunday about the threat.
Working with the school district, they identified the 15-year-old student and interviewed him with his parent.
Police say the student is currently not in school since it is the district's policy to suspend a student for such behavior. The school could seek long term discipline if warranted.
The student has been issued an appearance ticket to appear in Dutchess County Juvenile Probation and was transported to Mid-Hudson Regional Hospital for a psychiatric evaluation.
