The threats warn that bombs will be detonated if a certain amount of money is not paid.
Law enforcement officials are currently investigating numerous bomb threats being made across the U.S. on Thursday. There have been about 20 made in San Diego reports Fox 5.
The San Diego County Sheriff’s Department says they are aware of about 12 emailed threats, mostly sent to business across San Diego. One email was sent to a residence. They say they were able to determine that one was unfounded but continue to investigate others.
The San Diego police have also been getting alerts from concerned citizens within their jurisdictions.
Building managers are getting emails that say there are bombs in the building and if a monetary amount is not paid, they will be detonated reports San Diego police officer Joshua Hodge.
There were more than a half dozen of these threats made by 11:30 am. About nine businesses had been threatened by 11:50 am, many had evacuated the buildings while police were called.
So far, no devices have been found.
“We are going out to evaluate it like it is the real deal,” Hodge said. “They went into the buildings and they have not seen anything that would deem it to be a credible threat. However, they are still doing bomb-threat reports, because it is a crime.”
Sheriff’s Lt. Karla Menzies told The Tribune that people were getting calls in El Cajon and National City. “We are treating every call like a bomb threat,” Menzies said. “Once (businesses) are receiving the email, they are basically calling 911 to report it and we are responding as we can.”
The threats have been inundating the country and the FBI has become involved.
“We are aware of the recent bomb threats made in cities around the country, and we remain in touch with our law enforcement partners to provide assistance,” the FBI’s National Press Office told WSB-TV in Atlanta. “As always, we encourage the public to remain vigilant and to promptly report suspicious activities which could represent a threat to public safety.”
