NORFOLK – The third bomb threat in recent weeks at Norwood-Norfolk Central School resulted in an early dismissal of students in upper grades yesterday, but nothing more.

State police searched with a bomb-sniffing dog but found nothing of consequence, according to Superintendent Elizabeth Kirnie.

Kirnie said a student found some writing on a wall with a threat and reported it to a teacher.

She said the non-specific threat required that what has become “the routine of calling in the state police was done, as we take every such threat seriously.”

Kirnie said the threat was brought to light near dismissal time for upper grades, so those students were dismissed.

“The nature of the threat” led to a decision not to evacuate the elementary school, where classes were still in session.

She would not discuss the specific language used because the investigation is continuing, she said.

“These have not proven to be credible threats but are the kind of threat we have to take seriously and prosecute if necessary.

“It’s an additional stressor, and it takes law enforcement time” said Kirnie. “I know that’s why we have state troopers, but for something that could be just a student prank, it seems a shame to have to use these resources.”
