There was a school lockdown in North Haven Monday morning, but police said it was not credible.
A Facebook post from North Haven police said two students at the high school alerted a school resource officer about a possible threat and the schools were put in lockdown as police responded.
Investigators determined there was no threat to students in North Haven.
They said a student who is out of state on vacation read a post about a Middletown school threat investigation and sent a message telling her friends not to go to school Monday, which was reported to the school resource officer.
