South Korea’s anti-corruption agency has requested that police take over efforts to detain impeached President Yoon Suk Yeol after its investigators failed to bring him to custody following an hours-long standoff with the presidential security service last week.

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.
