Few days after wrestler Narsingh Yadav was found guilty of doping, another Rio Olympics-bound athlete Inderjeet Singh, a shot putter, has failed a dope test as his ‘A’ sample returned positive for a banned substance. The National Anti-Doping Agency(NADA) has asked Singh whether he wants to test his ‘B’ sample and if so, to do this within seven days. If the ‘B’ sample also tests positive, he will have to miss Rio Olympics beginning August 5, besides facing the prospect of being banned for four years.

However, Singh, who is a gold medal winner at the Asian Athletics Championships last year, pleaded innocence and said that he was a victim of a conspiracy.

“I am being targeted and it’s a clear case of conspiracy against me. My sample has been tampered with,” Singh said.

“Why would I take something which is not good for health?”

“I have been framed because I am outspoken,” the 28-year-old also said.

An Indian sports official, who wanted to remain anonymous, said Singh tested positive for the banned steroid Androsterone during out-of-competition testing by the NADA on June 22.

“NADA has informed Inderjeet about the result. If he wants to test his B sample then it has to be done within seven days,” said the official.

Earlier, Rio-bound wrestler Narsingh Yadav, a Commonwealth Games gold medallist in the 74kg freestyle category, also failed a drugs test. The wrestler also cried foul, claiming his water and food supplements were contaminated with a banned steroid.

India is sending its largest ever Olympic squad of more than 100 athletes in hopes of improving her poor medal count and the latest setbacks will be a huge blow for the country. This is not the first time that the country has been rocked by such scandals. In 2011 six top Indian women runners tested positive for banned steroids.
