SEOUL - A Republic of Korea special counsel on Monday indicted former president Yoon Suk-yeol on charges of benefiting the enemy.

A spokesperson of Cho Eun-suk, special counsel leading the investigation into Yoon's insurrection and other charges, told a press briefing that the independent counsel team charged Yoon with a crime of aiding the enemy and abuse of power.

A former defense minister and a former counterintelligence commander were also indicted on the same charges.

The spokesperson noted that Yoon undermined the military interests of ROK by increasing the risk of armed conflict between the two Koreas with an aim of creating conditions for the martial law declaration.

The ousted leader was apprehended in the presidential office on Jan 15 and was indicted under detention on Jan 26 as a suspected ringleader of insurrection.

He was released on March 8 as prosecutors decided not to appeal against the court's release approval, but he was taken into custody again on July 10.

The constitutional court upheld a motion to impeach Yoon on April 4 over his botched martial law bid last December, officially removing him from office.
