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.

Supporters of impeached President Yoon Suk Yeol pushed past lines of police to enter the court, some destroying furniture and blasting fire extinguishers at officers trying to suppress them.

Yoon’s arrest could mark the beginning of a prolonged period in custody, lasting months or longer, as he faces the possibility of imprisonment on potential rebellion charges linked to his imposition of martial law on Dec.
