Syria's Ghfran Almouhamad, who competed in the women's 400 meters hurdles event, has been disqualified from the London Olympics after testing positive for a banned substance, the International Olympic Committee said on Saturday.
"Ghfran Almouhamad, 23, provided a urine sample on 3 August 2012 in London that indicated the presence of methylhexaneamine. The analysis of the B sample confirmed the results of the A sample," it said in a statement.
She had placed eighth in the second heat of the first round on Aug 5.
