SEOUL, Aug 7, 2025 (BSS/AFP) - South Korean prosecutors on Thursday requested an arrest warrant for former first lady Kim Keon Hee, a day after questioning her over a litany of allegations, including bribery and stock manipulation.

The move comes as former president Yoon Suk Yeol remains in detention over his declaration of martial law in December, which briefly suspended civilian rule before being overturned by parliament.

"We requested an arrest warrant for Kim at 1:21 pm (0421 GMT)," the special council said in a brief statement to reporters.

If granted, the warrant would mark the first time in South Korean history that a former president and first lady were both arrested.

The request came swiftly after the 52-year-old underwent hours-long questioning the day before.

"I sincerely apologise for causing trouble despite being a person of no importance," Kim said as she arrived at the prosecutors' office on Wednesday.

She denied the allegations during questioning, according to local media reports.

Controversy has long surrounded Kim, with lingering questions about her alleged role in stock manipulation.

A video filmed in 2022 showing her accepting a Dior handbag from a self-proclaimed fan reignited public criticism.

She is also accused of interfering in the nomination process for MPs in Yoon's party, a violation of election laws.

Yoon, as president, vetoed three special investigation bills passed by the opposition-controlled parliament that sought to probe the allegations against Kim, with the last veto issued in late November.

A week later, Yoon declared martial law.

Yoon, a former top prosecutor, was impeached and removed from office in April over his martial law declaration, prompting the country to hold a snap election in June.
