Seoul: Detained President Yoon Suk Yeol will not appear before investigators for questioning over his short-lived imposition of martial law, his lawyer said Sunday, after Yoon was formally arrested over his failed imposition of martial law last month.

According to Yonhap News Agency, Yoon's lawyer, Yun Gap-geun, stated that the president will not comply with the request for questioning by the Corruption Investigation Office for High-ranking Officials (CIO) at 2 p.m. Yoon was formally arrested earlier in the day after the Seoul Western District Court granted the arrest warrant requested by the CIO.

The CIO, which had faced challenges in investigating the defiant president, expressed "deep regret" that Yoon "appears to deny the rule of law" without any effort to "resolve the issue within the judicial system." The agency suggested that Yoon could pursue an appeal or remedy process to overturn the warrant within the judicial system.

The agency also noted the need for safety measures for investigators, as protesters stormed the court in protest against the warrant issuance, threatening police and law enforcement officers.
