Silat exponent Saiedah Said has been hit with a two-year ban after testing positive for the banned substances Nor-Sibutramine and OH-Nor Sibutramine, an oral anorexiant (appetite suppressor), at the 38th National Pencak Silat Championships on April 14.
This means she is ineligible to participate, as an athlete or support personnel, in any sport during the period of the ban.
Her results, medals, points and prizes attained at the National Championships have also been forfeited.
She has until June 17 to submit an appeal to the National Anti-Doping Appeals Committee.
Ms Yeo Say Po, Deputy Director of Anti-Doping Singapore, said: "Under the World Anti-Doping Code, the rule of strict liability states that it is ultimately the athlete's sole responsibility to ensure that anything that they ingest does not contain any prohibited substance.
"This case is a reminder to all athletes to be always mindful of what they consume to avoid falling foul of any anti-doping rule violation."
