In August 2023 the Athletics Integrity Unit (AIU), on behalf of World Athletics, reported an anti-doping rule violation against the Colombian Athlete John Tello Zuniga after his A and B samples tested positive for the prohibited substance Erythropoietin (EPO).
Following notification the Athlete timely admitted the violation in November 2023, waived his right for a hearing and accepted the sanction proposed by the AIU.
The AIU deems that the Athlete failed to demonstrate 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 13 December 2023 to impose a 3 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 25 August 2023.
