Yoon’s detention comes after a stand-off between South Korean investigators and his presidential bodyguards, who blocked earlier efforts to detain him.

Lawyers for impeached South Korean President Yoon Suk Yeol failed in their court effort to secure his release on Thursday, a day after he was detained at his residence for questioning over rebellion allegations linked to his martial law declaration last month.

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