The B samples of two Malaysian competitors who failed dope tests during November's Southeast Asian Games in Indonesia have also returned positive results, local media reported on Saturday.
The Indonesian SEA Games Organising Committee confirmed the result to the Olympic Council of Malaysia (OCM), a report in the Star Online newspaper said.
The OCM had notified the respective national sport federations after the A samples returned positive but the associations opted to wait for the result of the B sample before taking any action.
"I received a call confirming that the B samples had turned out positive as well. It's not shocking news as we were well aware that this could be the outcome," OCM secretary general Sieh Kok Chi was quoted as saying in the report.
"I will wait for the official letter before revealing the names of the athletes.
"I will forward the findings to the associations and also inform the South East Asia Games Federation (SEAGF) as only they have the authority to strip the medals from these athletes."
After the A samples tested positive, local media reports last month said that one of the athletes was a member of Malaysia's victorious 4x400 metre relay team and the other a bronze-medal winning weightlifter.
