Pyongyang, August 20 (KCNA) -- The Inchon Headquarters of the south Korean Confederation of Trade Unions held a press conference outside the Inchon Branch of the Intelligence Service on August 17 demanding the puppet authorities stop at once the conspiratorial suppression, according to the south Korean Yonhap News.

At the press conference speakers said that the "spy ring case" was faked up by the IS according to a prearranged scenario.
