A Korean resident in Japan suspected of having been involved in the abduction of a Japanese national in 1977 is also believed to have gathered military information for North Korea, investigative sources said Thursday.

The sources said the Korean man received spy training from a North Korean agent and collected information about the Self-Defense Forces and the U.S. forces stationed in Japan before the abduction of Yutaka Kume.

The agent, whose Japanese last name is Yoshioka and Korean name is Kim, is different from the North Korean agent Kim Se Ho, 74, who is suspected of abducting Kume from the Noto Peninsula in Ishikawa Prefecture at age 52 in September 1977.
