Olympic bronze medalist Ronald Levy has identified himself as the sprint hurdler whose A sample was found to contain a banned substance during a Jamaica Anti-Doping Commission test last month.
Levy took to social media to publicly announce that he was informed of the adverse analytical finding on November 2, having been tested out of competition last month.
He said he is awaiting the testing of his B sample and hopes to clear his name.
Levy won the 110-metre hurdles bronze medal at the Tokyo Olympics.
