For days and months it seemed the Kremlin was all geared up to shut Alexei Navalny, the principal critic of Russian President Vladimir Putin. But now it has started to widen its net to include more opposition leaders. On 1st of June, Russian authorities arrested one opposition activist and raided the homes of several others. Andrei Pivovarov, the head of the Open Russia movement was pulled off a plane at St. Petersburg's airport on 31st May. He was to be taken to Krasnodar in southern Russia as part of a criminal probe against him..Open Russia dissolved itself last week. Pivovarov announced that Open Russia was shutting down to protect its members from prosecution after the authorities had designated it as "undesirable."
