South Korea's chief prosecutor steps down over sex and bribery scandals involving subordinates

South Korea's chief prosecutor has stepped down over sex and bribery scandals involving his subordinates.

Prosecutor General Han Sang-dae's resignation Friday follows an investigation into a junior prosecutor accused of having sex with a suspect under questioning. A senior prosecutor was also arrested on charges he took bribes from businessmen.

Though he was not directly linked to the two cases, Han apologized for the scandals in a speech Friday.

Han was appointed by President Lee Myung-bak in August last year and has overseen an aggressive crackdown on people the government suspects of sympathizing with rival North Korea.

South Korea holds a presidential election Dec. 19. It's unclear who might replace Han.
