The IAAF ethics board today upheld the provisional suspension of Kenyan athletics chief executive Isaac Mwangi after he was accused of seeking bribes from two woman athletes. Mwangi was suspended in February after runners Joy Sakari and Francisca Koki Manunga said he sought bribes to reduce their four-year doping bans. The Kenyan official denied any wrongdoing and challenged the ban last month. An IAAF panel said however that while no formal charges have yet been made, "there is a prima facie case and one fit for further investigation against Mr Mwangi. The panel added that the integrity of the sport could be seriously undermined if IAAF did not maintain a provisional suspension.
