Police deem bomb threats to businesses across SF not credible

Police have determined that a chain of bomb threats sent over email Thursday morning were not credible after searching nearly 20 locations across San Francisco.

A seemingly random assortment of businesses around The City received an anonymous threat in the email at around 10 a.m., according to Sgt. Michael Andraychak, a police spokesperson. Andraychak said police have searched every business that reported the threat to authorities.

“No suspicious devices have been found,” Andraychak said. “If no device is found then I would have to say that it’s not a credible threat.”

The threats were not only reported in San Francisco but in other cities across the U.S. Andraychak said the San Francisco Police Department is cooperating with an FBI investigation into the emails.

In San Francisco, the locations included corporate offices, a technology company and a parking garage. Andraychak declined to provide details of the emails but said all were similar.

Ryan Grant, an employee at Amore Real Estate near the Marina, said he received a bomb threat in his email. The message had the subject line “Think twice.”

“There is an explosive device (Tetryl) in the building where your company is conducted,” the email read. “It is small and it is hidden carefully, it is not able to destroy the structure of the building, but if it detonates there will be many wounded people.”

The email demanded $20,000 be sent in Bitcoin by the end of the day.

“To be honest my office made a joke out of it just because we’ve all received scam emails before but never a threat as large as this,” Grant said. “Of course terrorism is no laughing matter, and I hope whoever is behind this scam is brought to light. I’m sure this email scared a number of San Franciscans.”

Supervisor Aaron Peskin said he was briefed on the matter by police, who told him that the email threats demanded $20,000.

As of morning, Peskin said the threats had been sent to four businesses in the Central Police District, four in the Southern Police District and one in the Richmond Police District.

Among the places that received the threats were One Maritime Plaza, an office tower in the Financial District, 360 Post St., a retail and office building in Union Square and 609 Sutter St., where the Marine’s Memorial Club is located, according to Peskin.

The Jewish Community Center, which is located on California Street near Presidio Avenue, posted on Facebook that the San Francisco Fire Credit Union across the street had received a bomb threat.
