FBI arrests woman accused of surveilling Taiwanese president's son for China

The FBI arrested a suspected Chinese agent at Los Angeles International Airport after she allegedly surveilled the Taiwanese president's U.S.-based son, law enforcement sources told CBS News.
Wanying "Heather" Zhang, an Irvine, California, realtor, was cuffed by federal law enforcement on Sunday before she boarded a flight to Shanghai, China, from LAX, on a charge of acting as an unregistered agent of a foreign government.
Zhang's husband Edric Ding, a realtor at the same firm, told CBS News when reached by phone Sunday: "I don't know anything yet," and declined to comment further.
