Nassau County police have charged a Long Beach teen after Long Beach High School officials said he wrote a threat of violence on a desk this week.

Police said they received a call that a threat or threats had been written on a desk in a classroom at about 8:40 a.m. at the high school on Tuesday. After investigating, police arrested an unidentified 15-year-old student.

In a statement posted on Facebook Monday night, Long Beach school Superintendent David Weiss said a message threatening violence against the high school Tuesday had been found on a desk Monday morning.

Weiss added that security was increased for the school on Tuesday. Students were required to enter through the school’s main entrance and bag checks were conducted throughout the day.

In a second statement the district posted Tuesday, Weiss said that more threatening language had been found on a desk Tuesday. School officials again reported the messages, and a person was arrested, he wrote.

A Nassau police spokeswoman said she could not confirm the Monday threat, saying it was the Tuesday threat that had led to the arrest.

The student was taken to Nassau County Police Department and charged with making a terroristic threat, which is a felony. He is scheduled to be arraigned on Wednesday at Nassau Family Court in Westbury.

“The district does not tolerate such threats, pranks and rumors,” Weiss wrote. “We suggest parents talk to their children about the severity of such behaviors and the potential long-term negative consequences associated with such actions.”
