Enraged by government inaction against WFI chief Brij Bhushan Sharan Singh, Dronacharya award-winning coach Mahavir Singh Phogat on Friday threatened to return his medals if justice is not delivered.

The country's premier wrestlers, including Olympic medallist duo of Sakshi Malik and Bajrang Punia and World Championship medallist Vinesh Phogat, have been sitting on a protest in the national capital since April 23, demanding the arrest of the Wrestling Federation of India Chief and BJP MP Singh for alleged sexual harassment of seven wrestlers, including a minor.
