Three of five Jamaican athletes who tested positive are now known

guardian.co.uk: "The names of three of the five Jamaicans known to have tested positive for a banned substance are now in the public domain after two more athletes confirmed they had been notified of their results. Allodin Fothergill and Lansford Spence – both 400m runners who were in Jamaica's 4x400m relay squad at last year's Olympics – tested positive for methylxanthine, a substance not explicitly listed on the World Anti-Doping Agency (Wada) prohibited list but falling within a category of stimulants banned by the agency. The Commonwealth Games 100m champion Sheri-Ann Brooks has also received notification."
