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.

South Korean law enforcement authorities have arrived at impeached President Yoon Suk Yeol’s official residence in the capital Seoul.

South Korean President Yoon Suk Yeol has been arrested for questioning, according to the country’s anti corruption agency, in the latest chapter of a weekslong political saga that began with the embattled president’s shock martial law decree last month.
