South Korea's Presidential Security Service chief resigned Friday and acting President Choi Sang-mok accepted it. President Yoon Suk Yeol remains in his fortified residence as law enforcement seeks to arrest him.

South Korean police has questioned the chief of the presidential security service as the two agencies clashed over attempts to detain impeached President Yoon Suk Yeol.

South Korea’s President Yoon Suk Yeol faces a new and potentially more robust attempt to arrest him for insurrection after a top investigator vowed to do whatever it takes to break a security blockade and take in the impeached leader.
