New Delhi, July 24 (IANS): Wrestler Narsingh Yadav has flunked a dope test for a banned steroid and his Rio Olympics accreditation has been reportedly withheld by the Wrestling Federation of India (WFI).

The Sports Ministry confirmed that a wrestler had failed a dope test but it did not name Narsingh, who booked the Rio berth after claiming a bronze medal in the 74 kg category at the World Championships in Las Vegas last year.

The National Anti-Doping Agency (NADA) conducted a random dope test on Yadav on July 5 at the Sports Authority of India's (SAI) regional centre in Sonepat.

The report of his 'A' sample test was positive. Later, he was called for his 'B' sample test, which also turned out to be positive.

"One wrestler has been detected by the National Anti-Doping Agency (NADA) as dope positive. An Anti-Doping Disciplinary Panel (ADDP) has been constituted by NADA to hear the case. Its first hearing was held yesterday in which the wrestler was given an opportunity to defend himself," the ministry said on Sunday.

"After the hearing, the panel has asked NADA for further reports. After these are received, the panel will hold further hearing in the matter. ADDP is headed by a legal expert and includes doctors and sportspersons."

Narsingh however, claimed that he has not taken any banned substance and allegd that there was a conspiracy against him.

"This is a conspiracy against me. I am sure the truth will come out," Narsingh told a news channel.

"I have never taken any banned substance. I know Indian Olympic Association will support me," he added.

IOA President N. Ramachandran said that Narsingh will have to go through the relevant legal process and no tainted sportsperson will be allowed to take part in the Olympics.

"If an athlete has tested positive, then the law will follow its course. The IOA will not allow any cheats to participate in the Olympics," Ramachandran was quoted as saying by a news channel.
