Plainview-Old Bethpage Middle School was evacuated Wednesday due to a threat made.
Students were taken to Mattlin Middle School accompanied by their teachers while Nassau County police searched the building.
There was also a scare at Amagansett Schools.
Police say the district got an email saying bombs had been placed not just in Amagansett Schools, but buildings across New York.
Nothing suspicious was found at any of the schools.
Gov. Kathy Hochul's office says similar threats were made across the state on Wednesday
