London, Jul 31 (IANS/RIA Novosti): Swiss footballer Michel Morganalla has been sent home Monday from the Olympics by his country's officials following a racist tweet.

A message posted Sunday on Morganella's Twitter account, which has since been deleted, called Koreans "retards" and said that they should "burn", according to images published by Swiss newspaper Le Matin.

Morganella's Switzerland team lost to South Korea 1-2 earlier Sunday in a group stage game.

"The Swiss football federation will not tolerate this behaviour. The team was informed about the behaviour of the player and now he is already on his way home," an unnamed spokesman for the Swiss Olympic team said in comments posted on the Olympic News Service.

Morganella had played in both of Switzerland's football matches so far.

Greek triple jumper Paraskevi Papahristou was dropped from her country's squad after making racially offensive comments on Twitter aimed at African immigrants Wednesday.
