Authorities detained Navalny outside his home June 12 after he called on protesters in Moscow to switch their planned demonstration route from Akademika Sakharova Prospekt to Tverskaya Street, a large and iconic thoroughfare that leads straight to Red Square and the Kremlin. The Moscow mayor's office had issued a permit allowing 15,000 people to march along Akademika Sakharova Prospekt, but Navalny made the street change after claiming officials had pressured suppliers not to provide audio and video equipment for the demonstration. Electricity to Navalny's Moscow YouTube channel was cut overnight, preventing protesters from livestreaming their march. In addition, authorities removed from two regional government websites Navalny's documentary accusing Prime Minister Dmitri Medvedev of corruption, dubbing its placement on the websites a hack. Authorities also detained some individuals or barricaded others in their homes ahead of the protests. Participation in the demonstrations was notable in both size and geographic scope.
