Nigerian gold medallist Chika Amalaha failed a drug test and has been provisionally suspended from the Commonwealth Games ongoing in Glasgow for the same.
The 16-year-old claimed a gold medal in weightlifting with a combined total of 196kg in the women's 53kg category.
Her 'A' sample was found to contain amiloride and hydrochlorothiazide, which are both prohibited as diuretics and masking agents, The BBC reported.
Amalaha will have a 'B' sample tested on Wednesday.
The Nigerian athlete won gold last Friday, as Dika Toua took silver to secure Papua New Guinea's first medal of Glasgow 2014, with India's Santoshi Matsa winning bronze.
Amalaha is the first athlete to fail a test at the Games, but Welsh 400 metre hurdler Rhys Williams and 800-metre runner Gareth Warburton both missed the competition after being charged with anti-doping rule violations, the report added.
