Impeached president being questioned over failed December martial law bid a month after a first arrest attempt ended in stalemate

South Korea’s impeached president, Yoon Suk Yeol, has been arrested and is being questioned over his ill-fated declaration of martial law last month, anti-corruption investigators said on Wednesday, bringing to an end an early-morning standoff outside his official residence in Seoul.

His detention makes him the first sitting president in the nation’s history to be arrested.
