Police investigate second threat at Kellenberg Memorial High School in two days

For the second day in a row, a caller to a crisis hotline claimed a bomb had been planted at Kellenberg Memorial High School in Uniondale, prompting Nassau County police to respond to the scene on Wednesday.

And for the second morning in a row, police said, officers were able to evacuate the building because they found no serious threat.

Police said the Department of Homeland Security had also been notified again and that investigators were trying to determine whether the two incidents were actually related.

Police said no arrests had been made. It was not immediately clear whether a suspect – or multiple suspects – had been identified.

Police said the threat was received at 6:38 a.m. and classes had not yet started, so the building did not need to be evacuated. The threat was received at 7:12 a.m. Tuesday, police said.

That threat was made through the 988 Lifeline Suicide & Crisis Hotline. Police said Wednesday's threat was also made through a crisis hotline, but could not immediately say if it was the same crisis hotline.

On Tuesday, Kellenberg's principal, Brother Kenneth M. Hoagland, said in a message to parents and guardians that the threat indicated that two armed intruders were hiding in a school bathroom. Police said the threat also included that bombs would be placed in the school.

Officials said Tuesday the threats were sent from a phone number in Oregon.

Officials evacuated the building and searched for suspects or an explosive device, but found nothing. According to the Kellenberg School, students and staff were allowed to return to the school grounds in time for the regular start of school.

There are not many students in the school yet, as classes do not begin until 8:10 a.m., said Chris Cartier, director of special projects at the high school. All students who were there have been sent to the nearby sports fields, Cartier said.

He added:T The police left the school at around 8:50 a.m.

Wednesday's threat is at least the seventh school-related safety incident on Long Island since most schools began fall classes last week, and at least the fourth in the past five days.

In Huntington Station, Suffolk County police parked additional patrol cars outside Stimson Middle School for the second day in a row on Tuesday after investigating an implausible social media threat Sunday evening.

“To ensure the safety of our schools, Suffolk County Police will be providing an increased presence in the community to increase security around our schools,” South Huntington Superintendent Vito D'Elia said in a letter to parents.

On Friday, an unidentified woman entered East Islip Middle School through an unlocked door before being escorted out by security guards.

Hoagland said in his message to parents that the school had been the target of “swatting” attacks, in which police are called to emergency calls that later turn out to be false.

“The school administration ensured that the police cooperated fully and escorted students who were just arriving or already in the building to the soccer field. As soon as we were able to communicate with you, we did so,” Hoagland said in a letter to parents. “I admire how the police consistently respond to such pranks with intensity, seriousness and great concern for every single person in the area.”
