An engineer who worked for defense contractor United Technologies in Connecticut has been charged with attempting to travel to China with stolen documents on the development of advanced titanium for U.S. military aircraft.
Federal prosecutors announced charges against 36-year-old Yu Long, a Chinese citizen and a lawful permanent resident of the United States who lived in New Haven.
Authorities say Long was arrested Nov. 7 at an Ithaca, New York, home, two days after he allegedly attempted to fly to China from Newark, New Jersey, with sensitive, proprietary material. The criminal complaint was unsealed Tuesday at a court hearing in Bridgeport.
Long's attorney didn't immediately respond to a message seeking comment.
Long worked as a senior engineer-scientist for UTC from August 2008 until May of this year.
