Suffolk Public Schools unfortunately did not escape a rash of threats made across the country on Thursday.

The Suffolk Fire Marshal’s Office is investigating the threats but so far found them not to be credible, according to a city news release.

The emails arrived in various Suffolk Public Schools email accounts on Thursday. The emails referenced payment in Bitcoin, a cryptocurrency, to prevent repercussions.

City spokesman Tim Kelley said he had no additional details and could not say what schools received the threats. School division spokeswoman Bethanne Bradshaw also said she had no additional information.

The Virginian-Pilot reported that several locations in Norfolk and Virginia Beach also received threats. Those places included the World Trade Center office building, the Chrysler Museum, the Dominion Tower office building, several insurance companies and even a home-based business. The Virginia Beach threats were made at the Hebrew Academy of Tidewater and the Strelitz Early Childhood Education Center, the Pilot reported.

Chesapeake’s Central Library and 10 locations in Newport News also received threats, the Pilot stated. Nationally, police in New York City, Florida and other states were responding to similar threats.
