Police have questioned a former senior Defense Agency engineering officer and searched his home on suspicion he gave copies of confidential submarine documents to an acquaintance who may have leaked the information to China, according to informed sources.
Investigators allege that the 63-year-old engineer copied documents on the submarines' strength to resist attacks and took them out without authorization around February or March 2000 while working at the Defense Agency's Technical Research and Development Institute, the sources said.
The police searched his home, current office and other places in the middle of March and confiscated his computer and a technical report on steel for submarines.
