S Korean quizzed over spy claims

A South Korean dissident who has come home after 36 years in exile is being quizzed by intelligence officials.

Song Doo-yul, a 59-year-old professor, has spent his third day under interrogation over his alleged links with North Korea.

He has been barred from leaving the country until 3 October.

In 1997, a North Korean defector said Mr Song had been spying for the North, but a South Korean court dismissed the charges last year for lack of evidence.

Mr Song was a high-profile opponent of the South Korean military government in the 1960s, and moved to Germany in 1967, where he now has citizenship.

The National Intelligence Service has obtained a warrant to detain Song for 48 hours if he refuses to respond to questions, but officials say he has co-operated so far.

He cancelled plans to visit South Korea twice last year after the National Intelligence Service made clear its intention to arrest and investigate him.

"I'm doing my best while acknowledging what I did. I'm now very tired of being questioned," Song told reporters outside NIS headquarters on Thursday.
