Olympic medal-winning Indian wrestlers have accused the chief of the sport’s governing body and several coaches of sexually harassing multiple female athletes, with the opposition questioning the government’s silence.

The wrestlers, led by Olympic bronze winners Sakshi Malik and Bajrang Punia, began protesting in the capital New Delhi on Wednesday after accusing the Wrestling Federation of India (WFI) President Brij Bhushan Sharan Singh of sexual harassment. The sit-in protest has continued on Thursday.

Singh, who has been heading the WFI since 2011, is a six-time member of Parliament from Prime Minister Narendra Modi’s Bharatiya Janata Party (BJP).

Commonwealth Games women’s gold winner Vinesh Phogat said that coaches and the WFI president have sexually harassed multiple girls
