KINGSTON, Nov. 21 (Xinhua) -- Jamaican sprinter Steve Mullings received a life ban by the Jamaica Anti-Doping Commission (JADCO) on Monday.

The decision came four days after Mullings, 29, was found guilty of taking the masking agent furosimide. He finished third in the 100m final at the Jamaican national championships on June 24.

It was the second failed drug test for Mullings, who was banned for two years in 2004 for an elevated level of testosterone, also at the Jamaican championships, while still being a student at Mississippi State University in the United States.
