South Korea’s impeached President Yoon Suk Yeol was formally arrested early on Sunday, days after being apprehended at his presidential compound in Seoul. He faces possible imprisonment over his ill-fated declaration of martial law last month.

SEOUL (Reuters) - South Korea's impeached president, Yoon Suk Yeol, will attend a court hearing on Saturday on investigators' request to extend his detention, his lawyer said. The hearing in a Seoul courtroom begins at 2 p.m. (0500 GMT).
