Daily Caller reports:

Pakistani-born Imran Awan, long-time right-hand IT aide to the former Democratic National Committee (DNC) Chairwoman, has since desperately tried to get the hard drives back, the individual told The Daily Caller News Foundation’s Investigative Group.

A high-level congressional source, speaking on condition of anonymity because of the sensitivity of the probe, confirmed that the FBI has joined what Politico previously described as a Capitol Police criminal probe into “serious, potentially illegal, violations on the House IT network” by Imran and three of his relatives, who had access to the emails and files of the more than two dozen House Democrats who employed them on a part-time basis.

Capitol Police have also seized computer equipment tied to the Florida lawmaker.

Awan’s younger brothers, Abid and Jamal, his wife, Hina Alvi, and Rao Abbas, Imran’s best friend, are also under investigation. There have been no arrests in the case.

There is also evidence of financial schemes that extend beyond the Capitol Police’s purview and may expand to Pakistan, where Imran spends significant portions of the year.
