Eight female badminton doubles players were disqualified from the London Olympics after trying to lose matches to receive a more favorable place in the tournament, Indonesia’s team leader said Wednesday.

The Badminton World Federation investigated two teams from South Korea and one each from China and Indonesia. It accused them of “not using one’s best efforts to win a match” and “conducting oneself in a manner that is clearly abusive or detrimental to the sport” in matches Tuesday night.

Erick Thohir, the head of Indonesia’s Olympic team, told The Associated Press that the Indonesian team will appeal. He also accused China of losing on purpose in the past.

“China has been doing this so many times and they never get sanctioned by the BWF,” Thohir said. “On the first game yesterday when China did it, the BWF didn’t do anything. If the BWF do something on the first game and they say you are disqualified, it is a warning for everyone.”
