South Korea's arrested President Yoon Suk Yeol does not intend to take part in a second day of questioning on Thursday, his lawyer said, further stonewalling a criminal probe into whether he committed insurrection with his martial law bid.

Impeached South Korean President Yoon is taken to a detention center over his imposition of martial law, after questioning by anti-corruption agency.

Yoon Suk Yeol became the first incumbent South Korean president to be arrested when he finally backed down on Wednesday in a weeks-long standoff with authorities investigating him over alleged insurrection.
