Swiss soccer player Michel Morganella has been expelled from the London Olympics for posting a racially charged tweet.
Following Switzerland's 2-1 loss to South Korea on Sunday, Morganella directed an offensive tweet at Koreans and was subsequently sent home by the Swiss Olympic Committee.
"Michel Morganella has discriminated against, insulted and violated the dignity of the South Korean football team as well as the South Korean people," said Swiss chef de mission Gian Gilli.
Morganella's Twitter account has been deleted.
"The Swiss Olympic Committee would like to apologize here and now, especially to the South Korean Olympic Committee and the South Korean Football Association for the behavior of our player," Gilli added.
Morganella, who plays professional soccer for the Italian club Palermo, is the second athlete to be kicked out of the London Olympics for a racial tweet. Last week, Greek triple jumper Paraskevi Papachristou mocked African immigrants living in Greece.
Switzerland, which is 1-1 in Group B, plays its next game Wednesday against Mexico.
