SEOUL — Ousted South Korean President Yoon Suk Yeol appeared for questioning on Saturday before a special prosecutor on charges of insurrection, stemming from his controversial imposition of martial law in December, according to reports from local media.

Yoon arrived at the Seoul High Prosecutors Office in southern Seoul, where he once served as a prosecutor, for a formal inquiry into his December 3 declaration of martial law.

The move came two weeks after a special counsel investigation was launched into his actions, Yonhap News Agency reported.

Despite a request from Yoon’s legal team for a private entry to avoid media attention, authorities denied the request and required him to enter through the main entrance.

Prosecutors said Yoon had previously ignored three police summonses.

The former president was removed from office in April by the constitutional court after it ruled his attempt to impose martial law was unconstitutional.

He was subsequently arrested in January and indicted on charges of abuse of power and leading an insurrection making him the first sitting South Korean president to be held in custody while in office.

Yoon was released from detention in March when a district court overturned his arrest and permitted him to await trial without being physically held in custody. — Agencies
