Authorities said the FBI raided a home in Fort Washington, Md., Thursday morning.

They would not say whose home was being raided or why because it is an active investigation.

Nicole J. Schwab, an FBI spokeswoman, said the agency was “conducting court-authorized law enforcement activity at that location, but we have no further comment at this point.”

The home is located along Devon Hills Drive and the raid started around 6 a.m., according to FBI officials.

The investigation is being overseen by the bureau’s Washington field office.
