Guinea's leading human rights group confirmed that a member of the country's paramilitary police unit was found guilty of raping a female demonstrator inside the national soccer stadium during a pro-democracy rally in 2009.

Security forces loyal to the country's now-deposed strongman encircled the stadium and opened fire on the thousands inside, in a massacre that shocked the region. Dozens of women were gang raped on the stadium turf.

Souleymane Bah, of the Guinean Observatory for Human Rights, said that the gendarme was charged on April 30. A justice ministry official, who spoke on condition of anonymity because he was not authorized to speak to the press, confirmed the information. The gendarme's name has not been made public.

It's among the first prosecutions following the 2009 massacre.
