CCSDPD says the threat started as a rumor, but then the 16-year-old suspect made a call into Rancho High School, so the threat was creditable. The student reported it to authorities.
Halifax Regional Police don't believe there is a threat to anyone's safety after a high school was placed on lockdown Friday afternoon.
"We have not been able to discern a viable threat at Santa Fe High School", SFPD spokesman Greg Gurule said.
He added that police were maintaining a presence at the school as a precaution.
"We understand that parents and students may be fearful and feel that they are doing the right thing by posting information they think may have validity", reads the message. "Regarding the postings this week, we want to assure you that district and local law enforcement officials have conducted an extensive investigation including interviews and a home search and have found no credibility to these postings".
A district police department provides daily services to campuses, and school staff undergo annual training on how to keep themselves and students safe in threatening situations. The student was isolated while the incident was investigated. The student has been charged with making a terroristic threat.
