Former South Korean President Yoon Suk Yeol is back in custody over an independent investigation into his declaration of martial law last year.

A South Korean court has approved the new arrest of former President Yoon Suk Yeol on charges related to his brief imposition of martial law in December, accepting a special prosecutor’s claim that he poses a risk of destroying evidence.

Former South Korean President Yoon Suk Yeol was back in a solitary jail cell on Thursday with basic food and a khaki prison uniform after prosecutors secured a new detention warrant over his bid to impose martial law last year.
