IAAF Council has banned member, David Okeyo, from track and field for life, for diverting hundreds of thousands of dollars.
The decision was announced by the IAAF ethics board. He was also formally expelled as an IAAF Council member.
According to IAAF, Okeyo, who was also secretary general and a vice president of Kenya's track federation, was found guilty of taking from money given to the federation by Nike, as far back as 2004.
He was suspended in 2015, and the three-year case was decided at a hearing in January and February.
Okeyo was accused alongside two other officials; former Athletics Kenya president and former IAAF Council member, Isaiah Kiplagat, and treasurer, Joseph Kinyua.
Kiplagat died in 2016, while Kinyua was found to be involved in diverting money meant for Athletics Kenya to a "clearance account" for the men's personal use. However, he was not bound by the IAAF ethics code at the time and escaped punishment.
Okeyo was fined $50,000, which he was ordered to pay to Athletics Kenya. He was ordered to pay another $100,000 in legal costs.
Okeyo has also been charged separately with extorting money from athletes, but the IAAF has not published its findings on that charge yet.
