Yoon Suk Yeol,South Korea's impeached president, plans to attend a court hearing on Saturday to fight a request by investigators to extend his detention on accusations of insurrection, his lawyer said.

South Korea’s impeached president, Yoon Suk Yeol, was detained in a major law enforcement operation at the presidential compound Wednesday, defiantly insisting the anti-corruption agency didn’t have the authority to investigate his actions but saying he complied to prevent violence.

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.
