Russia shows us the way.

Forced to march in a human chain and lined up with hands behind their heads, this is how to round up illegal immigrants Russian-style.

Moscow police launched a no-nonsense crackdown on suspected illegals working on stalls in a market.

Officers prodded suspects with batons and pinned them against police vans as searches were carried out.

Others were forced to keep their arms in the air while police looked for documents – or a lack of them.

The suspects were then frog-marched on to a police bus with their hands on the shoulders of the person in front, and driven away from the Teply Stan market to face a rapid expulsion from the country.
