There's a new charge for an Illinois man accused of taking trade secrets from his job with a New Jersey-based defense contractor.

Sixing Liu was arrested at his home in Deerfield, Ill., in March 2011 and accused of taking restricted military data and presenting it at two conferences in China the previous fall.

Liu worked at Space & Navigation, a New Jersey-based division of New York-based L3 Communications.

He was originally charged with exporting defense-related data without a license and lying to authorities.

In a superseding indictment released Thursday, he was charged with possessing stolen trade secrets.

The secrets dealt with technology that could be used for target locators and other military applications.

Liu's Chicago-based attorney didn't immediately return an e-mail requesting comment.
