The prosecutors chased him there. After an overnight standoff, Mr. Chun surrendered himself.
But unlike Mr. Yoon, Mr. Chun was out of office when he faced the insurrection charge. Mr. Yoon, though suspended, is still guarded with the full support of his Presidential Security Service, a government agency that hires teams of elite bodyguards and anti-terrorist experts selected from the police, military and other government services.
“People who have seen him rely on his bodyguards as a shield against his legal trouble will see him as a coward,” Mr. Lim said.
The investigators warned that they would charge the presidential bodyguards with obstruction of justice.
“We will do everything we can to provide security for the object of our service according to laws and principles,” the Presidential Security Service said in a statement.
Public surveys showed that a majority of South Koreans wanted Mr. Yoon ousted and punished for insurrection. But his governing party, which opposed his impeachment, denounced attempts to hold him.
