Moon Jae-in is the only living former South Korean president who has not been arrested, but he is not without suspicion.
On the 26th of last month, South Korean President Yoon Seok-yeol was indicted by the prosecution on charges of masterminding a civil war. This is the first time that a sitting president has been arrested and indicted in South Korea, but it is the first time that a former president has been arrested and indicted in South Korea.
