Olympic bronze medallist boxer Vijender Singh, who had been accused of taking heroin, has been cleared in an out-of-competition drug test. Recent tests conducted by the National Anti-Doping Agency (NADA) on Vijender and four others have proved a blank. Singh, who won a middleweight bronze at the 2008 Beijing Olympics, was ordered by the sports ministry to take a test after local police accused him of using heroin on several occasions amid allegations from a fellow boxer. "Vijender Singh, boxer, along with four others was subjected to an out of competition test for banned substances. A full menu test was conducted which included testing for psychotropic substances. Tests were only carried out on blood and urine samples," the ministry said in a release.
