A team of no fewer than eight FBI agents spent about two hours at the home on Moraga Way.
Periodically, they would bring out boxes of electronics, including a computer and what appeared to be hard drives.
Agents at the scene wouldn't say anything about the investigation, but FBI sources tell ABC7 News that this search is related to a broader investigation into theft of satellite signals, also known as satellite piracy.
"Satellite piracy is when a hacker or pirate uses technology to pirate or steal pay TV by creating a fake set top box access card," Jimmy Schaeffler, a satellite expert.
It's not clear what role the occupants of this house play in this investigation, Schaffler says pirating satellite signals requires immense knowledge of engineering and information technology.
