Commodore Nesiama Omatseye, Technical Director, Athletic Federation of Nigeria (AFN), said on Wednesday that he was disappointed that Vivian Chukwuemeka did not learn from her previous doping ban.
Omatseye told the News Agency of Nigeria (NAN) in Lagos on telephone, that his disappointment stemmed from the fact that she was supposed to be a role model to upcoming athletes.
NAN reports that the athlete was said to have used banned substances at the 2012 African Championships at Port Novo, Benin Republic which was confirmed after her B sample test came out positive.
"She was banned in 2009 and I was part of those who pleaded on her behalf, because she was a source of inspiration to our budding athletes.
"And I am disappointed that she still had to engage in such an act, in spite of her level of exposure to the long term effects of doping,"he said.
NAN reports that the gold medal winner at the 2000 Commonwealth Games at Manchester had earlier received a two-year ban.
The technical director stressed that the National Sports Commission (NSC) and the AFN had zero tolerance for doping amongst its athletes.
He warned all the federation's athletes, in particular, and Nigerian athletes, in general, to desist from such acts.
Omatseye added that the AFN had always engaged its athletes in seminars, to highlight the negative effects of doping on the lives and careers of athletes. (NAN)
"Both the NSC and AFN have zero tolerance on the ingestion of banned substances among athletes; thus the AFN constantly educates its athletes on the negative effects of doping.
"And on the type of drugs to be taken by athletes and in what quantity, so as to avoid failing doping tests.
"The federation has gone further to state that it will sanction any coach whose athlete is found to be culpable," he added. (NAN)
