SANTA ANA, Calif. (KABC) -- Authorities are investigating two separate bomb threats targeting election offices in Southern California.
Registrars of voters' offices in Orange and Riverside counties were evacuated Friday evening after bomb threats were sent via email, authorities confirmed.
No explosives were found in either building.
In Riverside, deputies responded just before 6:40 p.m. to the 2000 block of Gateway Drive and evacuated the Riverside County Registrar of Voters.
Around that same time, a similar threat was e-mailed to the Orange County Registrar of Voters in the 1300 block of Grand Avenue in Santa Ana, according to the Orange County Sherrif's Department.
Workers there were evacuated 15 minutes before ballot processing was scheduled to stop, officials said. Explosive detection dogs searched the building amid the investigation.
"The Orange County Registrar of Voters is committed to ensuring equal access to the election process, protecting the integrity of votes, and maintaining a transparent, accurate, and fair election system," Bob Page with the Registrar of Voters said in a statement. "We are working diligently to address this incident and keep all staff and members of the public who visit our office safe."
ABC News is reporting that these same types of threats have been happening at offices across the country.
