FBI agents are searching the One Judiciary Square offices of the D.C. Office of the Chief Technology Officer this morning. The FBI is being tight lipped about what they are searching for, telling Politico only that the search is part of “an ongoing investigation.” WTOP’s Mark Segraves has been Twittering from the scene, adding that agents have since moved from the 9th floor OCTO offices to the 10th floor of One Judiciary Square, which houses the Office of the Attorney General. Some employees in the building have been sent home, according to Segraves.

The Washington Post is reporting that an arrest has been made: Yusuf Acar, 40, an information systems security officer for the OCTO, was reportedly taken into custody at his D.C. home this morning by federal agents. Acar had worked for Vivek Kundra, D.C.’s former chief technology officer who was recently named President Obama’s federal chief information officer.

There’s not a lot of other information available at this point, but we’ll be sure to update when we hear more.
