From UPI, via Big News Network:
Investigators in Japan have said an engineer copied confidential documents on a submarine and gave them to an acquaintance who passed them on to China.
Kyodo News Service reports that the 63-year-old engineer has been questioned by police who also searched his home and office and seized a computer. The engineer, whose name has not been released, retired from the Defense Agency in 2002 after working on submarine structures for many years. He is now a consultant for a defense company.
