The chief of the presidential security service in South Korea, Park Jong-joon, resigned from his position amid a political stalemate as federal authorities seek to arrest the country’s impeached president.

South Korea’s acting leader has accepted the resignation of the chief of the presidential security service, Park Jong-joon, as he faced police questioning over how his forces blocked law enforcement efforts to detain impeached President Yoon Suk Yeol last week.

The Presidential Security Service is facing additional criticism over its move to block the enforcement of an arrest warrant for impeached President Yoon Suk Yeol on Friday, after it was revealed that its use of military personnel to do so came in the face of explicit opposition from the acting defense minister.
