Prince George’s County Executive Jack B. Johnson was arrested at his home Friday morning by federal law enforcement agents, and he is tentatively scheduled to appear in court on federal charges later Friday afternoon.

Johnson and his wife, Leslie E. Johnson, were taken away in handcuffs shortly before 1 p.m. Johnson, wearing a camel-colored suit and white shirt, did not address reporters’ questions. It is not known yet what they have been charged with.

Neither the FBI nor the U.S. Attorney’s Office in Baltimore would discuss the case, other than to confirm that a series of search warrants were served Friday at the Prince George’s County government headquarters and at the Johnson home.

Since taking office in 2002, Johnson has been linked to investigations by various authorities, including a pay-to-play accusation involving a county contract to lease office space and a broad FBI investigation involving a massive development project near the Greenbelt Metro station that Johnson had strongly backed.
