Disgraced former South Korean president Yoon Suk Yeol has officially been indicted, facing serious charges tied to his controversial declaration of martial law last year.

Yoon sparked a national crisis on December 3 when he deployed military troops to the National Assembly, attempting to block lawmakers from overturning his martial law order, a move widely condemned as an attack on democratic rule.

In an unprecedented turn of events, Yoon was taken into custody this January, becoming the first sitting president in South Korean history to be arrested while still in office. He had resisted arrest for weeks, using his presidential security team to keep authorities at bay.

Though released in March on procedural grounds, his legal troubles never went away. Last week, he was re-arrested amid fears he might tamper with evidence.

On Saturday, lead prosecutor Park Ji-young confirmed Yoon's indictment, stating he is charged with abuse of power, obstruction of official duties, and fabricating government documents. According to prosecutors, Yoon bypassed the legal protocol for martial law, including skipping a mandatory cabinet meeting, and faked endorsements from both the prime minister and the defense minister.

Despite refusing to cooperate with investigators since his detention, Yoon made a court appearance on Friday in a bid to overturn his arrest warrant. His lawyers argued he was suffering physically and had limited mobility, but the court rejected the plea.

Yoon is currently being held in solitary confinement under sweltering conditions, with only a fan to battle the summer heat as South Korea faces an intense heat wave.
