The federal indictment charges Xiang Dong Yu, aka Mike Yu, 47, of Beijing, China, with theft of trade secrets, attempted theft and hacking into a protected computer. It is alleged that as a product engineer at Ford for 10 years to 2007, Yu had access to trade secrets including design documents, and copied 4000 of them onto an external drive just before departing to a new job in China. He subsequently used them, says the indictment, to try to secure employment with a Chinese car manufacturer.

He was arrested at Chicago’s O’Hare International airport on entering the US from China.
