Authorities say bomb threats sent to dozens of schools, universities and other locations across the U.S. appear to be a hoax.
The New York City Police Department said the threats sent Thursday were meant to cause disruption and compel recipients into sending money and are not considered credible.
Some of the emails had the subject line: “Think Twice.”
The Palm Beach County, Florida, sheriff’s office and the Boise, Idaho, police said they had no reason to believe that threats made to locations in those areas were credible.
Across the country, some schools were closed early and others were evacuated because of the threats. Penn State University notified students via a campus alert. Near Atlanta, people were ushered out of a courthouse.
Law enforcement authorities across the United States are investigating bomb threats at multiple universities, media outlets and businesses.
Several locations across the country have reported receiving the threats through emails, which threatens to detonate an explosive if $20,000 in bitcoin is not received.
The FBI Washington Field office released a tweet stating they are "aware of the bomb threats and are encouraging the public to remain vigilant and report suspicious activities."
The New York City Police Department of Counterterrorism released a tweet stating that they are aware of the threats and asked the public to "say something if they see anything suspicious."
