Fencer loses bid for epee fencing gold after disputed semis loss
Britta Heidemann of Germany edged Shin 6-5 in extra time with a winning hit with one second remaining. Korea protested that the clock had stopped with one second remaining as Shin fended off Heidemann's attack three times, and that the German's hit came after the final second was up.
Judges deliberated for nearly 30 minutes before awarding Heidemann the win. The 25-year-old Shin collapsed onto the floor in tears. She later lost to China's Sun Yujie in the bronze medal bout.
As South Koreans lodged an official protest, Shin staged a sit-down protest long after her match had ended. She was eventually asked to leave and embraced her coach before departing the ExCeL Arena, with the crowd behind her.
South Korea has previously won fencing medals in men's individual epee, men's individual foil and women's individual foil.
South Korea has already been at the center of two high-profile judging controversies, involving freestyle swimmer Park Tae-hwan and judoka Cho Jun-ho.
Park had a false disqualification ruling overturned in a span of hours on Saturday in the 400-meter freestyle race. In Cho's judo contest Sunday, referees initially awarded him the victory over a Japanese opponent before the International Judo Federation (IJF) intervened and overruled the flag decision on the field of play.
