Nassau police kept watch on a New Hyde Park high school Thursday after a report of a threat to “shoot up” the campus, authorities said.

Officers arrived before the start of classes Thursday at New Hyde Park Memorial High School, where they monitored entrances and the school vicinity, police said.

There were no incidents, but the police presence came after a student on Wednesday told school officials that an unknown person had posted the threat on Snapchat, authorities said.

The high school is part of the Sewanhaka Central High School District, and in a statement, Superintendent Ralph Ferrie said the district was notified early Thursday of the Snapchat threat by the parent of a student at the high school.

“The police, working with the building and district administration, investigated this incident and were able to determine that it was not a student from New Hyde Park Memorial sending the Snapchat,” Ferrie said. “The safety and well-being of our students and staff continues to be our top priority.”

Third Precinct detectives were continuing to investigate and asked anyone with information to call Nassau County Crime Stoppers at 800-244-TIPS.
