Jamaican Olympic sprint relay gold medallist Nesta Carter has returned an anti-doping violation for the banned stimulant Methylhexanamine after the re-testing of 454 samples from the 2008 Beijing Games, two sources familiar with the case have told Reuters. The Jamaican team of Carter, champion sprinter Usain Bolt and two other sprinters had won a gold medal in the relay at the 2008 Olympics. The sources, who spoke on condition of anonymity, said traces of Methylhexanamine were discovered in Carter's "A" sample, part of a batch of 454 from the 2008 Games that the International Olympic Committee (IOC) ordered to be re-tested. Carter could face sanctions only if his "B" sample also tests positive for the substance. Reuters has not seen the laboratory results. Neither Carter, who won gold in the 4x100 metres relay with Jamaican team mates Usain Bolt, Asafa Powell and Michael Frater in Beijing, nor his agent replied to repeated requests for comment.
