Kaori Icho grabbed a slice of Olympic history as Japan swept all three women's wrestling gold medals on offer at Rio de Janeiro on Wednesday. Icho became the first woman in any sport to win four gold medals in individual events across four Games with her victory over Russian Valeriia Koblova Zholobova in the women's freestyle 58kg final. Icho joined five men to have won gold medals in individual events at four straight Olympics.
