Beijing, China (Sports Network) - Korea's Cha Dongmin and Mexico's Maria del Rosario Espinoza claimed the last gold medals awarded in taekwondo at the Beijing Olympics by winning the men's and women's heavyweight divisions Saturday.
Cha defeated 2004 silver medalist Alexandros Nikolaidis of Greece in the gold medal match of the men's over-80 kilogram weight class, scoring three points in the first round on the way to a 5-4 win.
Nikolaidis settled for his second straight silver medal.
In the first of two bronze medal matches in the men's heavyweight division, Cuba's Angel Valodia Matos attacked the referee after he was disqualified for taking more than the allotted one minute of injury time.
Matos, the 2000 gold medalist in under-80 kg class, kicked the match referee after the disqualification. His opponent, Arman Chilmanov of Kazakhstan, believed the Cuban fighter would not have been able to continue match anyway.
"To me it was obvious he was unable to continue," said Chilmanov. "His toe on his left foot was broken."
Chilmanov, who called Matos' behavior "unsportsmanlike," shared the bronze medal with the winner of the other third-place bout, Nigeria's Chika Yagazie Chukwumerije.
Espinoza beat Nina Solheim of Norway to win the women's over-67 kg division, rallying for three points in the third and final round to claim a 4-1 victory.
Brazil's Natalia Falavigna and Sarah Stevenson of Great Britain won bronze medals.
