President Yoon Suk Yeol was formally arrested on Sunday after a South Korean court issued a warrant that would allow the investigative authorities hold him in custody for at least eight more days and look into his martial law imposition in December.

South Korean President Yoon Suk Yeol has been detained after a massive law enforcement operation at the presidential compound that ended a weeks-long stand-off between his bodyguards and the country’s anti-corruption agency.

After lawyers of South Korean President Yoon Suk Yeol argued that his arrest on January 15 was unlawful, a photo spread in social media posts falsely claiming it showed a search warrant used to illegally detain him rather than an arrest warrant.
