Kenya Athletics chief executive officer Isaac Mwangi has been provisionally suspended by the IAAF amid an investigation into allegations of bribery.
Mwangi last week reportedly offered to step down following claims that he requested payments from two Kenyan athletes who were banned for failing drugs tests in order to reduce their suspensions.
He denies any wrongdoing and vowed to clear his name, but athletics' governing body the IAAF on Monday imposed a 180-day suspension on Mwangi.
IAAF president Sebastian Coe last week stated that he is ready to ban Kenyan track and field athletes from the Olympic Games if the African nation's athletics federation is deemed non-compliant with the World Anti-Doping Agency (WADA) code.
WADA recently stated that the Anti-Doping Agency of Kenya (ADAK) still has a lot of work to do in order to prove it is conforming to regulations amid allegations made against athletes and officials.
An IAAF statement released on Tuesday said: "The Chairman of the IAAF Ethics Board [formerly Ethics Commission], Michael Beloff QC, has today provisionally suspended Mr Isaac Mwangi, CEO of Athletics Kenya, from all offices or positions in either Athletics Kenya or the IAAF in the interests of the integrity of the sport.
"Mr Mwangi is provisionally suspended from any office or position in either Athletics Kenya or the IAAF which he presently holds and is precluded from assuming any new office or position in either organisation for a period of 180 days starting on 22 February 2016, pending investigation of a complaint made against him and information that the IAAF Ethics Board has seen.
"The Chairman of the Ethics Board has imposed this Order for Provisional Suspension having carefully considered the information referred to the Ethics Board, which discloses a prima facie case, i.e. a case warranting investigation, against Mr Mwangi in relation to potential subversion of the anti-doping control process in Kenya.
"The Ethics Board stresses that the imposition of an Order for Provisional Suspension in this case in no way prejudges the outcome of the investigation which will now be carried out by the Board's appointed investigator, Mr Sharad Rao. Mr Mwangi remains presumed innocent until the outcome of the investigation and the determination of any disciplinary charges which may follow from that investigation.
"The Ethics Board's appointed investigator, Mr Sharad Rao, is a former Director of Public Prosecutions in Kenya and the current Chairman of the Judges and Magistrates Vetting Board, established under the Constitution of Kenya. Mr Rao is also a member of the Court of Arbitration for Sport and of the Code of Conduct Commission of the International Cricket Council."
