South Korean investigators have sought an arrest warrant for suspended President Yoon Suk Yeol over this month's short-lived imposition of martial law, an official said on Monday, the first time an incumbent president has faced such action.

South Korean law enforcement officials have requested a court warrant to detain impeached President Yoon Suk Yeol as they investigate whether his short-lived martial law decree this month amounted to rebellion.

South Korean authorities asked a court to authorize a warrant for the arrest of suspended President Yoon Suk Yeol on insurrection allegations following a short-lived bid to impose martial law at the start of the month.
