Federal agents served search warrants at a tech company based in San Diego that has offices in more than 20 cities in the U.S. as well as China.
Agents arrived Thursday at Technology Integration Group (TIG) on Trade Center Street north of Miramar Road.
Workers at nearby businesses say the police activity started around 9 a.m. Thursday.
They watched as workers at the business gathered in the parking lot.
"I thought it was a fire drill," said one man off camera.
Others noticed the law enforcement jackets, some with "FBI" and realized it was something else.
At the same time, agents with the Department of Energy-Office of Inspector General, FBI and IRS Criminal Investigation served warrants on the TIG location in Albuquerque, New Mexico.

All officials would say only that the warrants were part of an ongoing federal investigation.
Neighbors say by midday it appeared most employees had left.
