A squad of agents armed with a search warrant and accompanied by agents from the Department of Energy showed up at the Solyndra campus in Fremont, which recently announced it was closing its doors because it was unable to compete with lower-priced imports from Asia.
"Everything is under seal," FBI spokeswoman Julianne Sohn told the San Jose (Calif.) Mercury News.
The newspaper said a Solyndra spokesman speculated the search had something to do with $535 million on loan guarantees the company had received from the DOE. There have also been concerns voiced about a potential buyer dismantling the company's production equipment and shipping it overseas.
Solyndra filed for Chapter 11 bankruptcy protection and also laid off more than 1,000 employees. The company had a skeleton staff on hand Thursday closing down the operations and handling the last of the accounting and human-resources paperwork.
