In the 2004 World Cup in Bangkok, Rathore had tested positive for 'A' sample, but the International Shooting Sport Federation (ISSF) cleared him after the double-trap ace returned negative for his 'B' sample.
The surfacing of the issue after a gap of nine years has surprised Rathore, who felt it was the handiwork of the National Rifle Association of India (NRAI) whose April 6 elections were declared "null and void" by the Delhi High Court last month.
"The events of today are a clear attempt to defame me to divert attention from Hon HC decision of nullifying NRAI elections. To rake up a non issue from 9 years earlier is vendetta and a last ditch attempt to protect the stranglehold over the NRAI," Rathore said in a statement.
"In 2004 the highest officials of the ISSF were absolutely convinced about my credibility and had cleared me. I am amazed at the resistance of a few NRAI officials to allow free and fair elections. These things won't stop like-minded athletes from trying to clean up Indian sports," the 43-year-old Colonel added.
"This is baseless. All I can say is that we are always with the athletes. We were with him back in 2004 and we are with him now," Raninder said.
