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.

South Korea's president Yook Suk Yeol has been arrested by anti-corruption investigators, following a weeks-long stand-off between investigators and his personal security detail. The 64-year-old, who plunged South Korea into political turmoil with his short-lived martial law declaration on 3 December, is the first sitting president to be arrested.
