A court in Siberia has sent activist Sergei Piskunov to pretrial detention on a charge of "sexual abuse" until at least April 12, activist Denis Shadrin told RFE/RL on February 15. It is not clear what the charge stems from, while Piskunov's associates told RFE/RL that he was detained on February 12 at a checkpoint along the Russian-Kazakh border on a charge of organizing an extremist group. In the past, Piskunov used to coordinate activities of the Golos (Voice) movement, which monitored elections in Kemerovo. To read the original story by RFE/RL's Siberia.Realities, click here.
