South Korea's police have been asked to arrest suspended president Yoon Suk Yeol, the Yonhap news agency reported on Monday. Dozens of investigators working for the Corruption Investigation Office for High-ranking Officials (CIO) attempted to execute a court warrant for Yoon's detention on Friday after he ignored three summonses for questioning over his botched attempt to impose martial law on December 3.

The chief of security for South Korean President Yoon Suk Yeol said on Sunday he could not cooperate with efforts to arrest the impeached leader, in remarks that could push the political crisis towards another high-stakes confrontation.
