St Kitts and Nevis sprinter Tameka Williams has been sent home from the Olympics after admitting to taking a banned substance, officials from the Caribbean nation confirmed on Sunday.
The St Kitts and Nevis Olympic Committee said in a statement released on the country's national athletics federation Facebook page that Williams, 22, left London on Saturday in connection with the case.
"The St. Kitts and Nevis Olympic Committee (SKNOC) has withdrawn sprint athlete, Tameka Williams, from its 2012 Olympic Team, effective, Saturday 28th July," the statement said.
"In discussion with team management, Ms. Williams volunteered information to the effect that she has been using a substance which the SKNOC considers to fall outside the internationally accepted Medical Code."
"All the necessary bodies have been duly notified. This matter will be concluded pending further investigations," the statement said.
