South Korea’s former first lady, Kim Keon Hee, was arrested late Tuesday over a series of charges, including stock manipulation, corruption, and election law violations, prosecutors said.

The arrest came shortly after the Seoul Central District Court reviewed and approved a request for her detention, citing the risk that she might destroy or tamper with evidence. Prosecutors submitted an 848-page report detailing her alleged illegal activities.

Kim, 52, now joins her husband, former president Yoon Suk Yeol, in detention. This is the first time in South Korean history that a former president and first lady are both behind bars.

The dramatic turn comes after Yoon was impeached and removed from office in April, following his controversial attempt to declare martial law last December, which was quickly blocked by opposition MPs.

Public scrutiny of Kim has been ongoing for years, particularly around allegations of stock market manipulation. Her reputation was further questioned in 2022 after a video emerged showing her accepting a Dior handbag from a pastor, reigniting criticism.

She also faces accusations of interfering in the nomination process for members of parliament in Yoon’s party, which is considered a violation of election laws.

Kim was questioned for several hours last week before prosecutors filed for her arrest. Upon her detention, her Presidential Security Service protection was immediately removed, and she was transferred to a small solitary cell about 20 kilometers from her husband’s detention facility.

Her cell, measuring just 10 square meters, includes a small table, a sink, and a toilet, but no bed, and she must wear a khaki prison uniform and take a mugshot. She can be held for up to 20 days while prosecutors prepare formal charges, and once indicted, she could remain in custody for up to six months.

Kim apologized to the public as she arrived at the prosecutors’ office, saying she was a “person of no importance” for causing trouble. Legal experts note that challenging the arrest warrant or seeking bail is unlikely, due to concerns about possible evidence destruction.

The case against Kim marks a historic low for South Korea’s former first couple, amid ongoing controversies over corruption, political influence, and financial misconduct.
