NEW DELHI (AP):

Osayomi Oludamola was stripped of her 100-metre Common-wealth Games gold medal yesterday, the same day organisers announced that a second Nigerian runner had tested positive for the same banned stimulant.

The Commonwealth Games Federation said Oludamola's "B'' sample had confirmed a positive finding for the stimulant Methylhex-aneamine. "With the 'B' sample confirming the results of the 'A' sample, the Federation Court determined that Ms Oludamola had committed an anti-doping rule violation and that she be disqualified from the games and all her competition results at the 2010 Commonwealth Games be nullified," the federation said in a statement.

Natasha Mayers of St Vincent and the Grenadines will be moved up to gold, Katherine Endacott of England will get silver and Bertille Delphine Atangana of Cameroon will be awarded bronze.

Also, Samuel Okon, a finalist in the men's 110-metre hurdles, was suspended after waiving his right to have his "B'' sample tested.

He was also disqualified from the games and his results were nullified, the federation said. Commonwealth Games Federation President Mike Fennell said yesterday that Okon, who was sixth in the 110 hurdles final last Friday, had also tested positive for Methylhexaneamine.

"It's a stimulant," Fennell said of the drug, which has also been found in samples from about a dozen Indian athletes in recent months. "At this stage, I cannot speak very definitively as to where it's coming from, but it appears to us that it may be coming from the use of supplements."

Fennell said the Nigerian team was investigating the two positives.

"We have already had discussions with the leadership of the Nigerian team, who are themselves very, very concerned about this matter. We are satisfied that they are taking this very seriously," Fennell said. "They are very concerned about this and they are doing their own investigations."
