The U.S. Federal Bureau of Investigation has raided the office of the Washington, D.C., CTO and arrested two men there, the FBI said.

The CTO's job was until recently held by Vivek Kundra, appointed last week by U.S. President Barack Obama to be CIO for the U.S. government. A White House spokesman didn't immediately respond to an e-mail asking for comment on the raid. A number of news reports have cited unnamed sources saying that Kundra is not a target of the FBI investigation that prompted the raid.

Arrested in connection with the raid were Yusuf Acar, reportedly an information security and contracting officer in the CTO's office, and Sushil Bansal, CEO of Advanced Integrated Technologies, a Washington-based tech services and outsourcing firm.

The CTO's office has used Advanced Integrated Technologies for several projects, including an IT security support contract announced in May 2008 and the installation of more than 20,000 McAfee software packages, announced in August 2008, according to information on the company's Web site.

Those contracts were awarded when Kundra was CTO.

The raid is part of an ongoing investigation, an FBI spokeswoman said. Early press reports said the two men were arrested on bribery charges, but the FBI spokeswoman said the charges are under seal and not yet public.

The Association of Indians in America's Washington chapter selected Bansal for its Entrepreneur of the Year Award last August.

A spokeswoman for Washington Mayor Adrian Fenty wasn't immediately available for comment.
