By Hyunsu Yim SEOUL (Reuters) -South Korean investigators will seek an extension of a warrant to arrest impeached President Yoon Suk Yeol, an official said on Monday, as an anti-graft agency asked police to take over efforts to execute the arrest of the embattled leader.

South Korean investigators have asked police to execute a warrant to arrest President Yoon Suk Yeol after their initial attempt last week ended in failure following an hours-long standoff with his security team.
