In Khabarovsk it has become a nightly ritual.
A small group of protesters gathers on Lenin Square before marching off through the city centre. Along the way, more people tag along. The chanting grows louder, as does the cacophony of car horns signalling approval.
The demonstrators, who are risking arrest, are shouting slogans in support of the local governor, Sergei Furgal. Last week he was detained by officers who had flown in specially from Moscow. Mr Furgal has been charged with involvement in multiple murders dating back 15 years. He denies it. He's now behind bars in the Russian capital. That has sparked anger in Khabarovsk.
