A pair of unrelated school social media threats led to an increased police presence and a Catholic school choosing to shut down for today out of an abundance of caution.

Both incidents were caused by social media posts seen Sunday afternoon.

In Freehold, the township schools superintendent sent out an email to parents alerting them of an apparent noncredible social media threat involving Saint Rose of Lima School in the borough.

The email said, "IMPORTANT ANNOUNCEMENT FOR MONDAY JUNE 6TH. We are contacting you today to let you know that there has been a threat issued that could be detrimental to the safety of our students and school. Out of extreme caution we are closing school June 6th, as we work with the Freehold Police Department who are investigating. You will receive an alert tomorrow with updates."

There is no word if parents received any additional alerts.

The superintendent said in his release to parents that the threat was found to be noncredible and did not include schools in Freehold Township. The superintendent added that the safety of staff and students consistently remains a district priority and that they would be vigilant today and every day schools are open.

In Mercer County, there was another threat Sunday afternoon. West Windsor-Plainsboro Regional School District was made aware of a threat posted to social media regarding its school community, specifically, High School North. School was in session today.

An active investigation is underway, and the district is working with both the West Windsor and Plainsboro police departments. The threat was determined to be noncredible and the source has been determined, with appropriate actions being taken by law enforcement.  Anyone with information is asked to reach out to police.

There will be an additional police presence within the district in the coming days.

Specifics from the apparent threats are not available.
