Lawyers for impeached South Korean President Yoon Suk Yeol failed in their court effort to secure his release on Thursday, a day after he was detained at his residence for questioning over rebellion allegations linked to his martial law declaration last month.

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.

Yoon Suk Yeol, who is facing insurrection charges after his effort to impose martial law last month, becomes the first South Korean president to be detained while in office.
