(KXXV/RNN) - The Waco, Killeen and Clifton Police Departments responded to multiple emailed bomb threats to several locations on Thursday.
According to police, at this time, the threats do not appear to be credible.
They said they will continue to take these types of threats very seriously, and none of the threats in the Central Texas area were valid.
Clifton police say that Fort Hood Military Police sent a bomb detection team of eight officers and bomb-detecting K9s to the Goodall Witcher hospital.
The hospital was put on a soft lockdown as the area was searched. Eventually, the facility was cleared and no explosives were located.
Authorities across North America responded to a wave of email bomb threats that flooded inboxes Thursday, threatening businesses, schools and newspapers.
The emails came with the subject line: “Think twice," or ”We can make a deal."
The threats came in the form of an email, demanding $20,000 in bitcoin, a digital currency.
