South Korean President Yoon Suk Yeol has been arrested for questioning, according to the country’s anti corruption agency, in the latest chapter of a weekslong political saga that began with the embattled president’s shock martial law decree last month.

Yoon, the country’s first sitting president to be apprehended, now faces the prospect of a lengthy prison term over potential rebellion charges.

Hundreds of law enforcement officials in South Korea have entered the residential compound of impeached President Yoon Suk Yeol in Seoul.
