Varanasi: The father of wrestler Narsingh Yadav and several of his supporters on Saturday staged a protest in front of Prime Minister Narendra Modi’s parliamentary office here at Ravindrapuri demanding a high-level inquiry into the doping scandal.

Pancham Yadav, father of the 26-year-old wrestler who tested positive in two dope tests following which his hopes of participating in Rio Olympics faded away, claimed that his son was “innocent” and had fallen a victim to a conspiracy hatched by the rivals to oust him from the games.
