Indian Amateur Boxing Federation (IABF) president Abhishek Matoria advised pugilist Vijender Singh to provide his blood and hair samples to National Anti-Doping Agency (NADA) and come clean on the matter.
Matoria, while speaking to a news channel, revealed that he is in constant touch with Vijender and had recently spoke to him on Holi.
Speaking on the subject, he said the Olympian medallist should 'provide the samples as and when required by NADA.'
Punjab police have claimed Vijender had consumed drugs 12 times as per the testimony of his sparring partner Ram Singh.
The sports ministry yesterday in a press release had asked NADA to conduct test on Vijender to conclude whether he consumed heroin or not.
However, the agency has refused to conduct any heroin tests citing World Anti-Doping Agency (WADA) protocol.
The reason behind the decision is the fact that heroin testing is not in their prohibited list and it does not form part of out of competition tests.
