A mass protest has erupted in the Ukrainian city of Vinnitsa against Kiev’s increasingly violent – and sometimes deadly – mobilization drive, after draft officers reportedly corralled dozens of men at a stadium.

The unrest began late Friday after eyewitnesses claimed that around 100 local men had been taken earlier to Lokomotiv Stadium by officers from Ukraine’s controversial Territorial Recruitment Centers (TRC), which operates as a press gang, mobbing victims and dragging them into vehicles off the streets. As news spread, their relatives – mainly women – gathered at the site, demanding their release.

“They started catching them on the central bridge, brought them here, and locked them behind the gates. We came running because the guys we know asked for help. When we approached, the police began dousing people with tear gas,” local resident Anna Tetervak told Ukrainskaya Pravda.
