A former officer with the U.S. Defense Intelligence Agency was arrested over the weekend for allegedly trying to spy on the United States for China, the Justice Department said on Monday. The Federal Bureau of Investigation took Ron Rockwell Hansen, 58, into custody on Saturday while he was on his way to the Seattle-Tacoma International Airport to get a connecting flight to China. The department said he has been accused of trying to transmit national defense information to China and with receiving "hundreds of thousands of dollars" while acting illegally as an agent for the Chinese government.
