The prosecution on Wednesday indicted Korean-German scholar Song Du-yul for violating the anti-communist National Security Law.

Prosecutors said that they decided to indict the dissident scholar as he showed little signs of regret over his past actions.

Song is accused of acting as a non-standing Politburo member of the North's ruling Workers' Party, spreading North Korean ideology abroad and visiting the communist state on more than 20 occasions on orders from Pyongyang.

The prosecution also added the charge of attempted fraud to Song for lodging a 100 million won compensation suit in 1998 against former Workers¡¯ Party secretary Hwang Jang-yop, for branding him a North Korean spy.

Hwang, who defected to South Korea in 1997, had claimed Song was in fact a candidate member of the North¡¯s Politburo under the alias ``Kim Chul-su.¡¯¡¯ But a South Korean court ruled later that there was no evidence to back the allegations.

``Song denies the charges against him but we decided to go forward with the indictment as we believe he acted as a Politburo member of the North¡¯s Workers¡¯ Party,¡¯¡¯ a prosecutor said.

During investigations, Song admitted under pressure that he had joined the Workers¡¯ Party and received thousands of dollars from Pyongyang but had continued to deny accusations that he had been formally elected as a Politburo member or participated in activities benefiting the North while residing in Europe.
