Navalny was stopped by police at passport control after returning from Germany, where he spent five months recovering from two assassination attempts that he blamed on the Kremlin.

The Kremlin has denied using a Soviet-era nerve agent to twice poison Navalny.

After speaking with law enforcement officials for more than two minutes, Navalny is seen going with them peacefully in a clip of the incident tweeted by his lawyer Kira Yarmysh.

The country’s prison service said he was detained for multiple parole violations and terms of a suspended prison sentence.
