4 arrested in alleged government bribery case

WASHINGTON (AP) - Two employees of the U.S. Army Corps of Engineers and two others have been arrested in a bribery and kickback scheme.

The top federal prosecutor for the District of Columbia, Ronald Machen, plans to announce the arrests at a news conference Tuesday afternoon.

The names of the defendants were not immediately released.

The other two under arrest are the director of contracts for a Virginia-based company and the son of one of the Army Corps employees.

A law enforcement official who spoke on the condition of anonymity says the scam involved more than $20 million in bribes and kickback payments, and promised payments.

The official was not authorized to discuss specifics about the case before the U.S. attorney's announcement.
