Reuters estimated up to 40,000 protesters gathered in Moscow. Authorities gave a figure of only 4,000 participants, while other estimates included 15,000 and 25,000 participants. Protesters began gathering at Tverskaya Street and Pushkinskaya Square, with a procession ending near Matrosskaya Tishina where Navalny was being held. Riot police in the city began breaking up the protest and detaining participants before it was scheduled to start. Alexei Navalny's wife, Yulia Navalnaya, was detained by police at the exit of Moscow's Teatralnaya metro station; she was released after being detained for 3 hours. Navalny's ally, Lyubov Sobol, was also detained shortly after arriving at Pushkinskaya Square and was later fined. Clashes between police and protesters broke out. In Tsvetnoy Boulevard, an FSB car was stopped by a crowd of protesters and hit with snowballs, with the driver of the car reportedly sustaining an eye injury. State media reported that around 40 police officers were injured. The Investigative Committee said that it opened a probe into instances of violence against police. Russian rapper Noize MC, rapper Vladi from the group Kasta, director Vasily Sigarev, writer Dmitry Bykov and others attended the protest in Pushkinskaya Square.
