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.

Lawyers for the former president argued that arresting someone who was already in detention went against both logic and legal precedent.

The probe against Yoon Suk Yeol's wife comes while he remains in detention. If the arrest warrant is granted, it will be the first time in South Korea that a former president and first lady were both arrested.
