Disgraced Belarusian shot putter Nadzeya Ostapchuk has turned her attention to Valerie Adams, accusing the double-gold medallist of also taking drugs.

Ostapchuk was this week stripped of her London Olympics gold medal after testing positive in two separate drug tests at the games, and New Zealand's Adams was then promoted to the top spot.

The controversy was today taken to a new level, with Ostapchuk now trying to taint Adams' name.

GETTY IMAGES FAILED TEST: Belarusian Nadzeya Ostapchuk celebrates after her throw of 21.36m won her the shot put competition at the London Olympics, before a failed drug test saw her stripped of the title and gold medal.

She told Belarusian media Adams behaved in an unsportsmanlike manner during the Olympics.

"She was not even in starting line-up before the games, because she had a positive drug test in 2005," Ostapchuk said.

"I'm being covered in dirt, but someone else comes out all clean."

Drug Free Sport New Zealand chief executive Graeme Steel vehemently dismissed the accusations.

“Val has never failed any of our drug tests and the International Association of Athletic Federations are required to provide any tests of theirs that she fails. They have never done that,” he said in staunch defence of Adams.

Adams' manager, Nick Cowan, also rubbished the allegations in an interview with 3News tonight.

"She is obviously angry. She obviously has her own issues that she needs to deal with. She has been caught.

"She has a right to go through the process that she wants to go through, but she doesn't have a right to make slanderous comments."

Ostapchuk claimed doping was the real reason Adams was left off the start list, not an administrative error by the New Zealand Olympic Committee.

She said what Adams was saying about her was a joke.

"We will see how all of this will end, including for her."

OSTAPCHUCK POINTS FINGER AT FORMER COACH

Ostapchuk earlier said she was "framed" after testing positive for performance-enhancing drugs, pointing the finger at a former head athletics coach who was arrested this year by Russia's Federal Security Service.



According to Belarusian news website Charter 97, Baduyev was detained by the Federal Security Service - formerly known as the KGB - in May for extorting money from coaches and athletes by blackmailing them with the threat of positive dope tests.



In the interview with Pressball overnight, translated by Charter 97, Ostapchuk said she was a victim.



''The person [Baduyev], you know who I mean, the one who was involved in blackmail, he promised me long ago: you will have problems with doping control. Now I think his threat begins to come true, even though he no longer works with us.''



In reference to a wider conspiracy Ostapchuk said she would carry out her own investigation of the charges, including the ''participation of the investigating authorities''.



''Anything that will be learned during the investigation will be known to everyone. I have nothing to hide from people. I've spent a lot of efforts to become an Olympic champion, I do not need excuses. I do not want to finish a career like this,'' she said in the interview.



''Athletes need to know that there is someone to rely on, from whom they can receive support and advice. We want to feel protected instead of waiting for meanness from those who should help us.''



Meanwhile, the Belarusian government has come out in support of Ostapchuk.



An aide to the Belarusian president for physical education sport and tourism told the Belarusian Telegraph Agency the government would fight for Ostapchuk's gold medal.



Igor Zaichkov said their Olympic campaign was a ''disaster''.



"Both samples, A and B, tested positive. We will try to find out what happened and will investigate into the matter. Yet we will fight for Nadzeya Ostapchuk's medal and defend her interests,'' he said.



Zaichkov said their poor showing was not the fault of the athletes.



"They did not meet the Olympic medal plan. In some disciplines the performance was a complete disaster. The athletes are not to be blamed because they worked to the best of their efforts.



''This is the fault of some of our sports officials and coaches. In the near future we will hold a session to review the Games and make some personnel decisions.''



Adams will have a significant wait before she receives the gold medal.



The International Olympic Committee is working on retrieving Ostapchuk's, but said it could take some time now she had returned to Belarus.
