Botswana’s 2011 world 400m champion tested positive for methylhexaneamine at the Glasgow 2014 Commonwealth Games
Amantle Montsho has been handed a two-year doping ban after testing positive for the banned stimulant methylhexaneamine at the Glasgow 2014 Commonwealth Games, news agency Xinhua has reported.
The 2011 world 400m champion, who was pipped to world gold in 2013 by Britain’s Christine Ohuruogu, failed a doping test taken after she finished fourth in the women’s 400m final in Glasgow last July. Montsho’s B sample, analysed at a laboratory in London in August, confirmed the A sample analysis.
Xinhua reported how the Botswana Athletics Association (BAA) delivered their verdict on the sanction at the end of February. The case with the IAAF is ongoing, however, as the window for appeal remains open.
As well as her 2011 world title, Montsho claimed 400m gold at the 2010 Commonwealth Games in Delhi and has won three 400m titles at the African Championships, in 2008, 2010 and 2012.
The drug methylhexaneamine has been linked to supplements, causing federations such as UK Anti-Doping and Athletics Australia to release warnings to athletes in 2010. It is present in products available over the counter, including weight-loss aids and energy-boosters.
