Three Brooklyn schools are upping security in response to a social media threat.
Students at Edward R. Murrow High School, James Madison High School and Midwood High School saw an additional police presence Friday following an apparent threat Thursday to shoot students at the schools.
Sources say it may have been an old comment that was re-posted.
Many of the students told NY1 that they thought it was a lot of fuss over nothing, but Police Commissioner William Bratton took a "better safe than sorry" approach.
"We always err on the side of caution, so we have certainly, in this day and age, responded as we have, with that caution, but based on the briefing I have, I think we'll identify the source of that, and that it was, in fact, not going to be a serious threat directed against those schools," Bratton said.
No arrests have been made, but police are investigating.
