CHICAGO (AP) — A federal indictment unsealed Monday accuses a Chinese telecommunications company of stealing technology from Illinois-based Motorola Solutions Inc., in another case highlighting longstanding fears about China pilfering vital U.S. business secrets to bolster its own economy.

The Chicago filing charges Hytera Communications Corp., Ltd., with conspiracy to commit theft of trade secrets, alleging it recruited several Motorola employees as part of the scheme. They are accused of accessing Motorola’s internal database, then described and even joked about plans to use the stolen material at Hytera.
