WAYNE — John F Kennedy Elementary School was placed on lockdown Tuesday morning after a false activation of the school district’s emergency alert system, the Wayne Police Department said in a post on Facebook.

“A false activation of the school district’s emergency alert system caused JFK School to be locked down this morning,” the post said. “School staff acted quickly to protect the students.”

Wayne police immediately responded and conducted a sweep of the school, according to the post. There is no emergency at this time.

It is unclear how the false activation occurred.
