In March 2023 the Athletics Integrity Unit (AIU), on behalf of World Athletics, reported an anti-doping rule violation against the Kenyan Athlete Nicholas Mboroto Kosimbei after his A and B samples tested positive for the prohibited substance Trimetazidine.
Following notification a provisional suspension was ordered. The Athlete filed a statement in his defence and explained that he underwent medical treatment in a clinic in Kenya for his chest pain .
The AIU had requested assistance from the Anti-Doping Agency of Kenya (ADAK) to investigate the Athlete's explanations. As a result the AIU rejected the Athlete's defence because of the inconsistencies in his explanations.
In May 2024 the AIU charged the Athlete with an anti-doping rule violation and thereupon he gave a prompt admission, waived his right for a hearing and accepted the sanction proposed by the AIU.
The AIU deems that the Athlete failed to establish that the violation was not intentional. Because he had signed and submitted the Admission of Anti-Doping Rule Violations and Acceptance of Consequences Form he received a 1 year reduction from the AIU.
Therefore the AIU decides on 18 June 2024 to impose a 3 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 24 March 2024.
