NAIROBI: Top Kenyan athlete Francisca Koki, suspended for doping, said that she and fellow runner Joyce Zakari were asked to pay nearly $50,000 in bribes to the national athletics federation chief to help the case. Sprinters Koki and Zakari, suspended for doping violations at the Beijing World Championships, claimed Athletics Kenya chief executive officer Isaac Mwangi asked them for the bribe but they were unable to pay. “The two of us were asked to give 2.5 million shillings ($24,000, 21,000 euros) each by the Athletics Kenya’s Isaac Mwangi,” Koki said. Mwangi has denied the claims. Both Koki and Zakari were each given a four-year ban after being found guilty of using a prohibited substance, Furosemide, in Beijing in August 2015.
