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 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.

Impeached South Korean leader Yoon Suk Yeol was arrested on Wednesday over his failed martial law bid, ending a weeks-long standoff with authorities and becoming the first sitting president to be detained in the nation's history.
