The Commonwealth Games Federation says a 16-year-old Nigerian weightlifter's backup doping sample has also come back positive for banned substances.

Chika Amalaha tested positive for diuretics and masking agents after winning the 53-kilogram (117-pound) division last Friday, becoming the youngest ever female to win a weightlifting title at a Commonwealth Games.

Amalaha was initially suspended on Tuesday after the "A'' sample tested positive for amiloride and hydrochlorothiazide, which are both banned by the World Anti-Doping Agency.

CGF chief executive Mike Hooper said Friday that the "B'' sample also tested positive.

Hooper says a hearing will take place Friday afternoon. No ruling has yet been made on stripping her medal.

Dika Toua of Papua New Guinea won silver and Santoshi Matsa of India earned the bronze.
