The teen was charged in Dutchess County on Sunday, Dec. 18.
The Franklin D. Roosevelt High School-Hyde Park student was taken into custody by Hyde Park Police after the school was made aware of the potential threatening statement toward the school, said FD Roosevelt Prinicipal Michael Ruella.
"The Hyde Park Police Department has investigated this situation, identified the student, and has taken the individual into custody to ensure that FDR High School remains safe," Ruella said in a statement to parents.
The school is open, but as a precautionary measure there will be additional police presence on Monday, Dec. 19, said Hyde Park Police Chief Robert Benson.
"Please know that the safety and security of all students and individuals that enter FDR High School is paramount and our top priority," Ruella said.
Benson did not offer information on what type of threat was made or how.
The teen was charged with making a threat of mass harm.
