Police in Irvington are investigating a threat that cleared a middle school in the township earlier today.
Irvington Township officials said shortly before noon, a caller phoned in a threat that an explosive device was inside the University Middle School.
Officials evacuated the building and the neighboring University Elementary School was also evacuated as a precaution.
After a search of both schools, no such devices were found.
Officials believe juveniles called in the threat using an app, but the investigation remains active and ongoing.
