The incident occurred in Sullivan County on Saturday, Oct. 19, in Fallsburg.
According to Fallsburg Police Chief Brendan Pavese, the juvenile allegedly made the threats on Snapchat and included a picture of the Fallsburg Junior/Senior High School auditorium.
The threats, which mentioned shootings, came to the attention of police and school authorities via parents and students, both the police and school said.
After receiving the information, the police department worked around the clock and followed up on as many leads as possible to determine the credibility, if any, of the online threat.
The student, when identified, was brought to the police by their parents and arrested, the chief said.
The student, whose gender was not revealed, will appear in Family Court, he added.
"Our school community and law enforcement partners have no tolerance for threats (specific and/or non-specific) that target our school district and the people in it," said Dr. Ivan Katz, superintendent of the Fallsburg Central School District.
Katz added that the school community should continue to be vigilant and report any threats as quickly as possible.
"This needs to continue so that we can keep each other safe," Katz added.
