In India, several female athletes including a wrestler have returned their medals to highlight sexual harassment.

Vinesh Phogat, one of India's most decorated women wrestlers, left two prestigious awards on a roadside kerb after she was refused permission to meet Prime Minister Narendra Modi.

She and several wrestlers accuse former Wrestling Federation of India chief Brij Bhushan Singh of sexually harassing women wrestlers for years.

Phogat had won medals at the World Championships, Commonwealth Games and Asian Games.
