Kenya has arrested three top members of its Olympic committee after mismanagement of the contingent nearly derailed the country’s participation in the Rio Games.

The East African nation notched up its biggest ever haul of medals in Brazil but doping and organisational challenges had plagued its preparations in the run-up to the event, Reuters reported.

On Friday, Chef de Mission Stephen Arap Soi and Assistant Secretary of the National Olympic Committee of Kenya (NOC-K) James Chacha were taken to a police station in Nairobi upon arrival from the Olympics, alongside the body’s Secretary General F. K. Paul.

Another official, Chief Executive of Athletics Kenya, Susan Kamau, told Reuters she too was questioned by police but released later.

With six golds, as many silvers and one bronze medal, Kenya finished second only to the United States in the athletics table, making South America’s first Olympic Games its best outing so far.
