SAN FRANCISCO, CALIFORNIA, UNITED STATES (DECEMBER 13, 2018) (NBC) –
A rash of bomb threats were emailed on Thursday (December 13) to hundreds of businesses, public offices and schools across the United States and Canada demanding payment in cryptocurrency, but none of the threats appeared credible, law enforcement officials said.
The security scare began shortly before 2 p.m. EST (1900 GMT) as police departments in major U.S. cities coast to coast began reporting on Twitter that numerous local businesses had received the menacing emails – awkwardly worded threats to set off a bomb unless a bitcoin payment of $20,000 were received.
Four hours into the security scare, no actual explosives had been found, authorities said. But thethreats prompted brief evacuations of a Toronto subway station and a newspaper office in Raleigh, North Carolina. Some public schools and businesses also were evacuated as a precaution.
Among other cities where bomb threats were reported by authorities were Washington, New York, Detroit, San Francisco, Los Angeles, Oklahoma City, Denver, Ottawa, and Calgary, Alberta.
