President Isaiah Kiplagat and two other Kenya Athletics officials have been provisionally suspended for 180 days by the ethics commission of the IAAF.
Athletics’ world governing body is looking into allegations of “subversion” of the anti-doping process in Kenya and “improper diversion” of funds received from Nike.
Athletics Kenya vice-president David Okeyo and ex-treasurer Joseph Kinyua have also been provisionally suspended.
Their suspensions begin immediately.
The IAAF is also investigating Kiplagat in relation to alleged receipt of an apparent gift of two motor vehicles from the Qatar Association of Athletics Federation in the period 2014-2015.
Okeyo, who is also an IAAF member, was referred to the organisation’s ethics commission after being investigated by police in his native country.
He is alleged to have siphoned off funds from a sponsorship deal between the national association and American sportswear firm Nike.
Okeyo has denied any wrongdoing and said all funds had been fully accounted for by Athletics Kenya and audited.
The IAAF’s ethics commission has appointed Sharad Rao – a former director of public prosecutions in Kenya – as its investigator.
