Moscow police carried out yet more raids targeting migrants and marketplaces Wednesday, detaining hundreds of people. A special sweep operation involving some 400 police officers took place at the Sadovod market, a sprawling area in southeastern Moscow trading a variety of goods that employs many migrants. Over 1,000 people have been held there as of Wednesday morning, the police reported, but they did not say on what grounds they were detained. The operation is part of the city’s recent drive to “decriminalize” Moscow with checks of market places and other sites which house and employ many migrant workers. The city’s law enforcement authorities detained thousands of people in a string of raids, launched last week, following an attack on a police officer who was seriously injured at a Moscow market when attacked by an angry mob as he was trying to arrest a rape suspect.
