A suburban Chicago man accused of taking restricted military data to China has been granted bail, pending an appeal from federal prosecutors.

Sixing Liu, also known as Steve Liu, faces one count of exporting defense-related data without a license.

Authorities say the Deerfield man, formerly employed by a New Jersey technology company, took documents from his work on military navigation systems to China. He was speaking at a technology conference there.

Liu was stopped last November after flying to the United States from Shanghai. Authorities say he had restricted data and images for a Department of Defense navigation system on his personal laptop.

U.S. Magistrate Judge Sheila Finnegan in Chicago set Liu's bond at $200,000 Wednesday and gave New Jersey prosecutors 24 hours to appeal the ruling.
