The Seoul Central District Court announced on Friday it has extended former President Park Geun-hye's detention period, for a maximum of six months.
The court said the decision was made due to the severity of the case and to prevent Park from destroying evidence.
Prosecutors had requested last month for an extension on Park's detention period, which was set to expire on October 16.
The disgraced leader was indicted in April on a total of 18 charges, including bribery and corruption.
Legal experts expect the first ruling on Park's case to come out by the end of November.
Meanwhile, Samsung Electronics Vice Chairman Lee Jae-yong had his first appeal trial on Thursday.
Lee was sentenced in August to 5 years in prison after being convicted of a string of crimes, including bribery, embezzlement and perjury. Lee's legal team filed for appeal, arguing that the Samsung heir-apparent is innocent on all the charges.
