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.

South Korea looks set for a dramatic political showdown this week as impeachment proceedings kick off against suspended President Yoon Suk Yeol, who remains holed up in his fortified residence evading arrest for a separate criminal investigation.
