The Presidential Security Service (PSS) on Tuesday raised the possibility of blocking the second possible attempt to detain impeached President Yoon Suk Yeol, saying a forced entry into Yoon's residence would be "illegal" and it will respond in line with its security protocols.

The Presidential Security Service is facing additional criticism over its move to block the enforcement of an arrest warrant for impeached President Yoon Suk Yeol on Friday, after it was revealed that its use of military personnel to do so came in the face of explicit opposition from the acting defense minister.

A new attempt to arrest South Korean President Yoon Suk Yeol is under way, six weeks after his short-lived attempt to impose martial law.
