South Korea’s impeached President Yoon Suk Yeol was formally arrested early on Sunday, days after being apprehended at his presidential compound in Seoul. He faces possible imprisonment over his ill-fated declaration of martial law last month.

A South Korean court on Sunday extended President Yoon Suk Yeol's detention for up to 20 days, leading to violent protests by hundreds of angry supporters who stormed the court building, smashed windows and broke inside.

A Seoul court issued a warrant Saturday to detain impeached President Yoon Suk Yeol for an extended period over his botched martial law bid last month in the first such detention of a sitting South Korean president.
