Narsingh Yadav case goes to CBI

​New Delhi: The Central Bureau of Investigation registered a case on Tuesday to probe the circumstances of Narsingh Yadav's failed dope test. The wrestler had requested for CBI intervention in the failed dope test case. Narsingh had tested positive for methandienone -- a banned anabolic steroid. The 26-year-old has maintained that the substance was mixed in his food by rivals.

Yadav was later handed a four-year ban by the Court of Arbitration for Sports in August that prevented his participation at the Rio Olympics. In its full award, the ad hoc panel of the CAS relied on expert evidence that Narsingh's dope offence was not due to one-time ingestion of the prohibited substance and its concentration in the first test result (of June 25)was so high that it had to come from an oral ingestion of one or two tablets of methandienone, rather than from a drink where the powder had been mixed with water.

The expert opinion was given by Professor Christiane Ayotte from Canada who was presented by the World Anti-Doping Agency. Professor Ayotte is a member of IAAF Doping Commission since 1995 and was elected representative of the Heads of IOC Accredited Laboratories in 1995-1996. She is currently the Director of the WADA accredited laboratory in Montreal.

Narsingh's urine sample taken out-of competition on June 25 was found to contain long term metabolites of methandienone. Another sample taken out-of competition on July 5 was also found to contain long term metabolites of methandienone. "...all in all found the sabotage (s) theory possible, but not probable and certainly not grounded in any real evidence. The panel therefore determined that the athlete had failed to satisfy his burden of proof and the panel was satisfied that the most likely explanation was that the athlete simply and intentionally ingested the prohibited substance in tablet form on more than one occasion," the CAS panel said.
