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.

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 as investigators widened their insurrection probe.
