India's top wrestlers, who have been protesting against BJP MP and chief of the country's wrestling federation Brij Bhushan Sharan Singh, accused of sexually harassing several women wrestlers, including a minor, today said they will "immerse" their medals in the Ganga river at the holy city Haridwar in Uttarakhand as they feel it has "no meaning" any more, and is only being used as a "mask" for propaganda by the system.
