BROOKLYN, N.Y. (WABC) -- A teenager was being questioned Wednesday about threats made against Bishop Loughlin Memorial High School.
The 15-year-old boy was picked up by detectives after a Facebook post was discovered that advised others not to go to the Brooklyn school because there would be a shooting. The post was quickly taken down.
Bishop Loughlin, which is in Clinton Hill, canceled classes as a precaution after the threat was posted.
Detectives from the New York City Police Department's Intelligence Division are investigating.
A letter sent home to Loughlin parents clarified that the teen being questioned does not attend the school and explained the decision to close Wednesday.
"When faculty arrived at school early this morning they were informed of a threat. I was called and the administration decided to act cautiously to secure the safety of our students given the nature of the threat," said the letter from Bro. Dennis Cronin, school president.
It said that the situation should be resolved soon and that Thursday should be a normal school day.
"The nature of the threat was such that we deemed it important to act cautiously on behalf of our students and so, via our website, we canceled school for the day," said Cronin.
Cronin would not go into detail about the threat and what exactly it said.
But according to students, it involved a post making the claim that the school would be "shot up" Wednesday, a claim that scared a lot of students.
"I called my father and he was very concerned," said one student. "He thought I was lying, but he checked his e-mail and the e-mail said there was an emergency at the school and classes were canceled."
The NYPD maintained a heavy presence at the school throughout the morning.
School officials say canceling classes was the right thing to do. "Where we are today, I think it requires that we are on the side of safety, so whether it was credible or not I have no idea. But I do know it was a threat and the primary concern is the safety of our students and that will always take precedence," said Cronin.
He said no threat was made against any student, the threat was to the building.
