Doping and corruption allegations are threatening to destroy Kenya’s chances at the ongoing Rio Olympic Games in Brazil after a second ‘Team Kenya’ official was sent home for posing as a runner during a doping test.

John Anzrah, a former sprinter and part of the coaching staff was found in possession of the accreditation badge of Ferguson Rotich, an 800 meters runner who was set to undergo an out-of-competition doping test, before competing in the preliminary round later on Friday.

He allegedly provided urine sample for the runner which is a doping violation and was sent home by Athletics Kenya on Thursday, Sky News reported.

“The problem with John Anzrah is he took possession of an identity card (accreditation) of an athlete who was in the list of World Anti-Doping Association (WADA) for out of competition dope testing,” Stephen Arap Soi, Kenyan Team leader said.

“He was taken to the doping control station purportedly as Ferguson Rotich and subjected to produce the sample and he signed. The crime he has committed (is) against Team Kenya and that is why we are sending him back home,” added Arap Soi

The incident comes a week after Michael Rotich, was captured by investigative journalists asking for $13,000 in bribes from coaches for giving advance warning before doping tests between January and February this year in Kenya, The Sunday Times reported.

Rotich was sent home from the Olympics Village and has since been arraigned in court, as Kenyan authorities seek to reign in on errant sports officials involved in doping violations.

The two incidents have placed one of the world’s most dominant middle and long-distance running nations under increased scrutiny, sparking fears that her athletes might have benefited from doping in past competitions.

As the athletics competitions start tonight in the Brazilian capital, Kenya faces a battle off the field to redeem her athletics reputation in the wake of the doping and corruption allegations.

In May, WADA had placed Kenya in the list of non-compliant nations, but cleared the nation after parliament passed the anti-doping law a month later.

The Kenyan government has vowed to crack the whip on the officials.
