As of my knowledge cutoff in October 2023, there are no reports of South Korean President Yoon Suk-yeol being impeached or detained by the Corruption Investigation Office for High-ranking Officials (CIO). President Yoon assumed office in May 2022, following a successful election campaign, and continues to serve as the nation’s leader.
The CIO is a relatively new institution in South Korea, established to investigate corruption among high-ranking officials. Its actions are significant in the country’s efforts to promote transparency and accountability within the government. However, there have been no official statements or credible news reports indicating any legal action against President Yoon.
It’s possible that new developments have emerged after my last update. For the most recent information, it’s advisable to consult reliable news sources or official government statements.
