South Korea’s impeached president, Yoon Suk Yeol, has been formally arrested, days after being apprehended at his presidential compound in Seoul.

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.

A South Korean court issued a warrant to formally arrest impeached President Yoon Suk Yeol over his ill-fated attempt to declare martial law last month.
