July 16 (Asia Today) -- The South Korean government apologized Thursday over allegations that police mishandled and concealed aspects of the Jang Yun-gi murder case, announcing plans for an external investigative body staffed largely by about 100 civilians.

Interior and Safety Minister Yoon Ho-jung announced measures to eradicate corruption in police investigations and strengthen democratic oversight during a public address at the Government Complex Seoul.

"The head of the investigative team in the Jang Yun-gi case has been arrested on suspicion of destroying evidence and indications of deliberate collusion and preferential treatment by the investigation team are emerging one after another," Yoon said.

"I offer my deepest condolences and sympathy to the victim's family and sincerely apologize for causing concern to the public," he said.
