South Korean investigators have called in arrested President Yoon Suk Yeol for questioning again, the Yonhap News Agency reported, as authorities face a Friday deadline to obtain a warrant to extend his detention or release the embattled leader.

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.

Yoon was brought into custody about three hours after hundreds of law enforcement officers entered the residential compound in their second attempt to detain him.
