In May 2017 the National Doping Control Commission of Chile (CNCD) has reported an anti-doping rule violation against the cyclist Raúl Arturo Ladrón de Guevara after his A and B samples tested positive for the prohibited substance Clenbuterol.
After notification a provisional suspension was ordered and the Athlete was heard for the Disciplinary Panel of the Tribunal de Expertos en Dopaje (TED).
Despite the Athlete's denial of the violation the Panel holds that he failed to produce evidence in support of his defence. The Panel concludes that the Athlete committed the anti-doping rule violation.
Therefore on 10 November 2017 the TED Disciplinary Panel decides to impose a 4 year period of ineligibility on the Athlete starting on the date of the provisional suspension, i.e. 14 May 2017.
