South Korea's impeached President Yoon Suk Yeol attended a court hearing on Saturday to fight a request by investigators to extend his detention on accusations of insurrection, his lawyer said. Yoon on Wednesday became the country's first sitting president to be arrested,

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.

Suspended South Korean president Yoon Suk Yeol once again refused to appear for questioning on Friday, the third day of his detention, as investigators requested he be formally placed under arrest, the country's Yonhap news agency reported.
