Running great Kip Keino has handed himself over to police in Kenya, is under arrest and set to face corruption charges that threaten the reputation of one of track and field's most revered figures.
The 78-year-old Keino, former Kenyan sports minister Hassan Wario and two other former sports ministry officials surrendered to police in Nairobi on Thursday.
They are due in court Friday to plead to the charges relating to the misuse of more than half a million dollars meant to fund Kenya's team at the 2016 Rio de Janeiro Olympics.
Keino was president of the Kenyan Olympic committee at the time.
A two-time Olympic champion, Keino is an honorary member of the International Olympic Committee and was one of the first athletes to be inducted into track and field's half of fame in 2012.
He was the forerunner for generations of Kenyan distance-running champions, winning gold in the 1,500 metres at the 1968 Mexico City Olympics.
He is accused of playing a role in the misappropriation of more than $US545,000 ($A762,346) of government money set aside for Kenyan athletes at the Rio Games two years ago.
Keino and six other current and former Olympic and government officials were accused by prosecutors of the embezzlement of more than $US200,000 ($A279,760) and misuse of more than $US300,000 ($A419,640).
The Daily Nation newspaper in Kenya reported that Keino will be charged with giving his son nearly $US25,000 ($A34,970) of Team Kenya's money for an air ticket to Brazil and spending money in Rio.
Details of a chaotic Kenyan Olympic trip emerged in 2016, with allegations of joy riders being given thousands of dollars in allowances and hundreds of thousands of dollars and equipment meant for Kenyan athletes disappearing.
Despite that, Kenya finished second in the track medals table and had its most successful Olympics.
