In 2015, following the Moscow government’s refusal to establish a memorial at the site of Nemtsov’s murder, the slain politician’s supporters organized networks to maintain a makeshift shrine, regularly stocked with flowers, pictures, and candles.

The city regularly sends police and cleanup crews to remove the memorial and the volunteers who maintain it are regularly harassed by pro-Kremlin activists.

Russian Internet users in February shared footage of one of the sweeps, showing city workers tossing flowers, candles and portraits it into the back of a truck.

At the end of the video, a man dressed in civilian clothes then chases down the cameraman, apparently attacking him.
