South Korean officials say the organizing committee for the 2018 Winter Olympics in Pyeongchang has been under investigation over its preparations for the games.

Tuesday's confirmation by the Seoul-based Audit and Inspection came one day after the resignation of organizing committee chief Kim Jin-sun.

Kim stepped down Monday, saying new leadership is needed to complete preparation for the Olympics. South Korean media have reported he was fired by the government over poor preparations for the games.

Audit officials say the weeks-long inspection of the committee that ended on July 11 looked at financing and management.
