Former South Korean President Yoon Suk Yeol failed for a second consecutive day to appear for questioning by special counsel Min Joong-ki, deepening legal troubles linked to multiple investigations involving him and his wife.

Yoon, currently in custody over an alleged attempt to impose martial law in December, was summoned to Min’s office by 10 a.m. Wednesday for questioning related to his alleged interference in the 2022 parliamentary by-elections.

His aide cited deteriorating health as the reason for his nonappearance. “He has difficulty moving and even sitting upright, making it unlikely he can attend unless his condition improves,” the aide told Yonhap News Agency.

Yoon also ignored Tuesday’s summons. In response, Min’s team has warned it may now seek a detention warrant to forcibly bring him in for questioning. If granted, investigators plan to send a team to the Seoul Detention Centre, where Yoon is being held, to carry out the order.

Yoon was arrested on July 10 after a court issued a warrant on charges related to his alleged martial law plot, part of a broader probe led by special counsel Cho Eun-suk into potential insurrection and related offenses.

Meanwhile, Min’s team is independently investigating corruption allegations tied to Yoon’s wife, Kim Keon Hee. These include claims that the couple received free opinion polling services from political broker Myung Tae-kyun ahead of the 2022 presidential election, in exchange for a political nomination.

The former president is also accused of violating election laws by allegedly making false statements during the 2021 presidential primaries to deflect his wife’s suspected involvement in a stock manipulation case.
