Lawyers for impeached South Korean President Yoon Suk Yeol are denouncing efforts to detain him over his short-lived imposition of martial law, while the country’s acting leader expressed concern over a possible clash between law enforcement agents and presidential security personnel.

The effort to detain Yoon came after a South Korean court issued an arrest and search warrant on Dec. 31 over his short-lived imposition of martial law, ABC News confirmed. Yoon has been suspended from his position since Dec. 14.
