Four South Korean badminton players have returned home after their disqualification from the Olympics for trying to lose matches.

The two women's doubles pairs arrived Saturday in Incheon International Airport and left through undesignated gates as they tried to avoid media. The athletes did not comment.

Two other doubles teams, from China and Indonesia, were also disqualified this week for deliberately playing poorly to secure a more favorable draw in the next round.

The International Olympic Committee is demanding further investigation by national Olympic committees. South Korea's Olympic delegation ordered the four players and their coach to return home, saying they violated the Olympic spirit of fair play and sportsmanship.
