Law enforcement authorities have requested a warrant to formally arrest impeached South Korean President Yoon Suk Yeol, who is spending his third day at a detention center after his lawyers failed in a last-minute attempt to secure his release.

Yoon Suk Yeol became the first South Korean leader to be held by criminal investigators, ending a long standoff after he imposed martial law.

Yoon became the first sitting South Korean president to be arrested. South Korean investigators probing Yoon for alleged insurrection asked a Seoul court on Friday to extend his detention after he refused to be questioned.
