Translation: ‘At the headquarters right now’
Lyaskin said that around 10 policemen were on the premises.
During the night, bars were put on the windows of the headquarters on the Sadovnicheskaya embankment, and lights were switched off, Lyaskin wrote later on Twitter.
Similar altercations with the police have taken place this month in Navalny’s election headquarters in Novosibirsk and Oryol.
Navalny led a series of demonstrations throughout Russia this year against corruption and has said he will run in presidential elections in 2018.
