The IAAF has provisionally suspended the chief executive of Athletics Kenya amid allegations he asked athletes for bribes to reduce doping bans.
The governing body for athletics said it took the decision concerning Isaac Mwangi “in the interests of the integrity of the sport”.
Meanwhile, Kenya has been given until 5 April to show it complies with the World Anti-Doping Agency (Wada) code.
If it fails to do show it could be banned from international athletics.
In regards to Mwangi, an investigation into “potential subversion of the anti-doping control process in Kenya” will now take place.
He denies wrongdoing and said he had wanted to leave his post for 21 days to clear his name prior to the IAAF announcing his suspension.
Wada said it was “most disturbed” by the claims.
“The allegations have caused me a lot of mental anguish,” Mwangi said in a letter to Athletics Kenya.
