police mark. Reporter Kim Chang-gil: As suspicions about the poor investigation of the Jang Yoon-ki case spread into suspicions of collusion and corruption within the police organization, the police established a ‘police investigation reform task force’ centered on external personnel. It was also decided to establish a new internal corruption investigation unit directly under the head of the National Investigation Headquarters. On the 9th, the National Police Agency said, “In relation to the Jang Yoon-ki case, the police appointed an external person in exile as the chairman to prevent recurrence of similar cases and prepare a stricter control plan for the police investigation.”
