Nairobi: Kenya's Daniel Wanjiru, a former London marathon champion, is the latest casualty to have failed a doping test.
Wanjiru joins a ballooning list of Kenyans who have been caught cheating as the Athletics Integrity Unit (AIU) tightens the noose. However, Wanjiru is adamant he is innocent.
AIU announced on Tuesday the provisionally suspension of Wanjiru with immediate effect after his Athlete Biological Passport showed variations, which is a violation under the World Athletics Anti-Doping Rules.
"There was a violation of Wanjiru's Athlete Biological Passport (ABP), which monitors athletes' selected biological variables over time," AIU said in a statement.
"In doping cases, a Provisional Suspension is mandatory under the World Athletics Anti-Doping Rules following an adverse analytical finding for any non-specified substance on the Prohibited List," it said.
However, Wanjiru in his defence said he is innocent and will prove it before AIU.
"I am clean in the sports I do. The ABP finding is confusing and frustrating me. Specialists have informed me about how this can happen and I have come to realize there can be hundreds of reasons found why HB is fluctuating. I feel I am already seen as a sinner of doping, but I am not. I am innocent. It's very painful what's happening to me now," said Wanjiru on Wednesday in Nairobi.
