Seoul: Former President Yoon Suk Yeol plans to attend a court hearing on the legality of his arrest later this week, his lawyers said Thursday. The hearing, which has been scheduled for 10:15 a.m. Friday at the Seoul Central District Court, will review whether the former president's arrest was legal and should remain in place.

According to Yonhap News Agency, Yoon decided to attend the hearing to personally explain his health condition, which he claims makes it effectively impossible for him to attend his ongoing criminal trial or appear before the special counsel. His lawyer emphasized that Yoon's health has "seriously deteriorated."

Yoon filed for the review on Wednesday, less than a week after he was placed under arrest at the Seoul Detention Center in Uiwang, just south of the capital, over five key charges related to his attempt to impose martial law in December.

The court's decision, expected within 24 hours after the hearing, will determine whether Yoon will be released from the detention center or kept in custody until the end of a 20-day initial arrest period.
