South Korea's disgraced ex-president Yoon Suk Yeol was detained for a second time Thursday over his declaration of martial law and held in a solitary cell pending investigations into accusations of insurrection.

Yoon, who was the first sitting South Korean president to be arrested, faces trial on charges of leading an insurrection over his attempt to impose martial law. During Wednesday's seven-hour hearing, a special counsel team argued for the arrest warrant on five key charges, South Korean news agency Yonhap reported.

SEOUL, South Korea (AP) — A South Korean court early Thursday approved the new arrest of former President Yoon Suk Yeol on charges related to his brief imposition of martial law in December, accepting a special prosecutor’s claim that he poses a risk of destroying evidence.
