A Long Island school was at the center of yet another threat, this time at Northport Middle School.

Suffolk police say a threat made yesterday evening was deemed not credible. District officials say a student made a violent threat against the district and Northport Middle School, which prompted calls to police.

In an email sent to parents Wednesday night, the Northport-East Northport District Superintendent Dr. David Moyer said in part, "Unfortunately, situations of this nature are becoming all too common across Long Island and the country. Students must be aware of the very serious repercussions of such actions and making threats against the school or individuals."

Michele Pettignano-Coggins has two children at Northport Middle School. She says she’s heard from many parents since the email went out Wednesday night.

"Getting emails and texts from other parents, 'Do you know what's going on? Do you know what's going on?' I said, ‘We have no clue,’" she said.

Earlier this week, News 12 learned district officials found racist graffiti on bleachers at East Northport Middle School.

News of this recent threat comes as Suffolk police tell News 12 how many threats have been received this school year. Including this incident in Northport, Suffolk police have responded to 24 school threats this school year.

As previously reported, Nassau has seen at least 37 school threats.

Pettignano-Coggins says greater transparency about what's been going on could help them answer their kids' questions.

"We'd just like to know what's going on, which would be helpful so that we could help guide our kids,” she said.

District officials say action will be taken against the student who made the threat, but specific details about that action cannot be shared publicly.
