The FBI has moved into a massive glass complex in Sorrento Valley, Calif.
San Diego’s new headquarters opened among technology and biotech giants who have made that area popular.
The $120 million complex was aimed at improving security and providing ample space for the 400 or so special agents and other staff at the FBI, U-T San Diego reports.
Today is the first official day of business in the building.
The moment will be celebrated with a flag-raising ceremony.
