Leaders of Russia's opposition say they were being questioned for a second time just days after tens of thousands marched in Moscow's largest protest since President Vladimir Putin's return to the Kremlin.
Ex-deputy prime minister Boris Nemtsov, television host Ksenia Sobchak and liberal activist Ilya Yashin were interrogated Friday for their role in organizing recent rallies, including a May 6 protest that ended in violent clashes with police.
Earlier this week, police searched the properties of all three leaders and brought them in for questioning.
Sobchak tweeted she was brought into a "strange, damp room," where she was questioned about the $1.7 million in cash found in her apartment.
Yashin said he could only guess what the proceedings would entail, because the Committee would not discuss the "protocol" for investigation.
