Berkeley Heights Detectives simultaneously began their investigation and swiftly identified a person of interest. The person of interest was located in another jurisdiction and debriefed by investigators who have determined that the reported threat and subsequent reports were not credible. Once this was established, and there was no longer a threat, all schools were removed from lockdown and students were dismissed.

"We are thankful for the report from the student and parent as we encourage people that see something to say something. We also appreciate the patience and understanding of the parents and the students throughout this incident," said Captain Deitch.

 Out of precaution, neighboring New Providence School District also went into lock down.
