Lawyers representing South Korea’s impeached president said he will refuse further questioning after being detained by anti-corruption officials over his ill-fated declaration of martial law last month, maintaining that the investigation is illegal.

President Yoon Suk Yeol exercised his right to remain silent as he underwent more than 10 hours of questioning on Wednesday at the headquarters of the Corruption Investigation Office for High-Ranking Officials, following a massive law enforcement operation to detain him at his official residence in Seoul.
