Yoon, who was the first sitting South Korean president to be arrested, faces trial on charges of leading an insurrection over his attempt to impose martial law. During Wednesday's seven-hour hearing, a special counsel team argued for the arrest warrant on five key charges, South Korean news agency Yonhap reported.

South Korea's former President Yoon Suk Yeol will appear on Wednesday at a Seoul court, which will consider a special prosecutor's request to detain him as part of a probe into his botched bid to impose martial law.
