Federal investigators have arrested a former top procurement official in the Bush administration on charges of making false statements and obstructing an investigation.

David Safavian was arrested Monday, after resigning as head of the White House's procurement policy office on Friday.

Federal prosecutors charge that in his previous position, as chief of staff of the General Services Administration, Mr. Safavian concealed his efforts to help lobbyist Jack Abramoff buy real estate from the government.

Prosecutors also said Mr. Safavian denied Mr. Abramoff had any interest in doing business with the government, while seeking clearance to accompany Mr. Abramoff to Scotland for a golfing trip.

Mr. Abramoff is the subject of several investigations probing alleged fraud of Indian tribes who are his clients.  Congressional Democrats have raised questions about Mr. Abramoff's ties to House Majority leader Tom Delay (R-Texas).
