The embattled president had been holed up in his fortified residence for weeks surrounded by his Presidential Security Service team, evading arrest as he faces several probes and an impeachment trial.
The Corruption Investigation Office (CIO), which is working with police and the defense ministry to investigate Yoon, first attempted to detain him earlier this month, but it failed after an hours-long showdown in which soldiers and members of the presidential security detail blocked some 80 police and investigators from approaching the presidential compound.
