South Korean President Yoon Suk Yeol has reportedly been arrested by the country's Corruption Investigation Office for high-ranking officials, making it a first for a sitting South Korean leader. Yoon is facing charges of insurrection following his unsuccessful proclamation of martial law on Dec. 3, which carries a maximum penalty of death. The execution of the presidential arrest warrant is underway, enabling Yoon to be detained for up to 48 hours under the current warrant. Yoon's legal team has criticized the warrant as unlawful, while an investigation is ongoing to determine if his martial law declaration constituted an attempted uprising.
