Moscow police have detained hundreds of mostly migrant workers in raids on city markets in the wake of an attack in which a police officer was injured.
A police spokesperson said some 470 people were detained at three markets.
On July 27, a group of police officers was attacked by two dozen people at the Matveyevsky market in western Moscow as they were detaining a man suspected of raping a 15-year-old girl.
One police officer sustained a severe head injury.
In response, police launched sweeps to check people working at city markets for involvement in crimes and offenses.
The rape suspect and a man suspected of attacking the police officer were detained.
Moscow's markets employ many migrants from other former Soviet republics and Russia's Muslim-populated North Caucasus.
