South Korean president dismisses spokesman over 'unsavory incident'

Seoul, South Korea (CNN) -- President Park Geun-hye of South Korea has dismissed her press spokesman after concluding that he was involved in an "unsavory incident" during a state visit to the United States, her office said.

The spokesman, Yoon Chang-jung, "showed inappropriate conduct as a high-ranking official and damaged the dignity of the country by being personally involved in an unsavory incident," the chief presidential press secretary, Lee Nam-ki, said in a statement Thursday from Los Angeles.

The South Korean Embassy in Washington is investigating the incident, Lee said without providing further details on what Yoon is alleged to have done.
