More than 200 people, many of Central Asian origin, were arrested at the complex underneath the Cherkizovsky Market.

The underground network even contained a casino, canteen, cinema and a chicken coop.

It is thought that the network of caves and rooms were used to service an army of clothing manufacturers.

Moscow draws millions of migrants from the former Soviet republics in Central Asia, who often work to send money to family back home.
