Chinese man held for exporting US military know-how

Liu Sixing, also know as Steve Liu, was arrested at his home in Deerfield, Illinois and charged with one count of exporting defense-related technical data without a license, the Justice Department said in a statement.

Liu, a Chinese national with permanent residency in the United States, worked for the New Jersey-based company from March 2009 until November 2010 as a senior engineer on a team developing precision navigation devices.

According to the charge, he boarded a flight from Newark last November to China, but on returning from Shanghai he was found to have a non-work issued computer containing hundreds of documents about the company's projects.

There were also images of a presentation Liu made to a technology conference which was organized by the Chinese government, the statement said.

Liu was never issued with a company laptop, and did not have the authority to access the company data outside of its New Jersey facility.
