The VP reported that seven locations in Norfolk alone had been shut down due to emailed bomb threats, plus others in neighboring cities like Hampton Roads and Virginia Beach.
Some of the emails have the subject line "Think Twice."
The sender then demands a ransom in $20,000 worth of bitcoin by the end of the day, providing a BTC address.
Slightly different versions of the email have been reported, with small changes in wording, such as the material the bomb is reportedly made out of.
However, police across the country have urged that "the email is not a credible threat," according to a notice sent out to University of Washington staff.
"We are currently monitoring multiple bomb threats that have been sent electronically to various locations throughout the city," the New York Police Department's Counterterrorism Division said on Twitter. "These threats are also being reported to other locations nationwide & are NOT considered credible at this time."
Police further urge people not to pay the ransom.
Some of the affected locations include universities, courthouses, newspaper offices and corporate offices in New York, New York; Olympia and Seattle, Washington; Boise, Idaho; San Francisco, California; State College and Philadelphia, Pennsylvania; Orlando and Palm Beach, Florida; and Park City, Utah, among numerous other locations.
Streets in Washington, DC, were shut down as well, with police blocking road traffic and advising pedestrians to stay indoors.
Police on K Street near the White House told a Sputnik reporter they were "working on a bomb threat" late Thursday afternoon. The all-clear notice was given not long after.
