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.

Yoon has been lying low at his official residence in Hannam-dong, an upscale district popular with business tycoons and celebrities known as Korea's Beverly Hills. Meanwhile, investigators seeking to question him on allegations of insurrection have struggled to execute a warrant for his arrest.
