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.
