A South Korean court gave authorities approval on Tuesday to detain impeached President Yoon Suk Yeol in a criminal investigation into his martial law decree, marking the first time that a sitting president of the country has faced arrest.
The Corruption Investigation Office for High-ranking Officials (CIO) confirmed the Seoul Western District Court approved an arrest warrant requested by investigators examining Yoon's short-lived imposition of martial law.
Yoon, who has been suspended from office, is facing investigation on allegations that he was the leader of an insurrection, one of the few criminal charges from which a South Korean president does not have immunity. Separately, his trial on impeachment is being heard at the Constitutional Court.
The arrest warrant for an incumbent president is unprecedented, and deepens the political crisis that has engulfed South Korea, Asia's fourth-largest economy and a key U.S. ally.
Prime Minister Han Duck-soo, who took over from Yoon as acting president, has also been impeached by parliament, which is dominated by the opposition.
Finance Minister Choi Sang-mok, who took over as acting president after Han's impeachment, has been dealing with Sunday's crash of Jeju Air flight 7C2216, which killed 179 people in the deadliest air disaster on South Korean soil.
The current arrest warrant is viable until Jan. 6, and gives investigators only 48 hours to hold Yoon after he is arrested. Investigators must then decide whether to request a detention warrant or release him.
