New Delhi: Disgraced and banned for four years from Olympics the alleged dope-tainted Indian wrestler Narsingh Yadav on Friday pledged to take his battle to the Prime Minister’s Office.

Narsingh’s dream to represent India in the Rio Olympics crumbled as Court of Arbitration for Sports (CAS) slapped him with a ban of four years.

“My name has been tarnished, not just me, this ban is a blot on India. Let me be hanged, I will take this to higher courts and will leave no stone unturned,” the 74kg freestyle wrestler told PTI in Rio.

“I will appeal to the Prime Minister to investigate this matter thoroughly. The truth must come out, even if we need CBI for that. If I’m the culprit, hang me, I’m ready for it. Do a NARCO test on me and also the people who are involved.” Narsingh Yadav told PTI.

Earlier, Narsingh had claimed that his drinks/food were spiked during the pre-Games training in Sonepat by unknown persons, which was agreed to by the National Anti-Doping Agency (NADA).
