South Korean police questioned the chief of the presidential security service on Friday as the two agencies clashed over attempts to detain impeached President Yoon Suk Yeol.
The Corruption Investigation Office for High-Ranking Officials and police are planning a second attempt to bring Yoon into custody as they jointly investigate whether his brief martial law declaration on Dec. 3 amounted to an attempted rebellion. The presidential security service blocked an earlier attempt to detain Yoon at his official residence, which he has not left for weeks.
