South Korean President Yoon Suk Yeol has been arrested for questioning, according to the country’s anti corruption agency, in the latest chapter of a weekslong political saga that began with the embattled president’s shock martial law decree last month.

The Corruption Investigation Office for High-ranking Officials will likely seek a new court warrant to extend the window for Yoon’s detention, according to police.

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.
