MOSCOW, September 3 (RIA Novosti) – Russian police discovered 42 immigrants living and working at a Defense Ministry facility in the Moscow Region, the Interior Ministry announced Tuesday.

“Police officers have found 42 citizens of former Soviet republics living and working on the grounds of the facility. The building in which they were working was rented by a firm specializing in metal manufacturing,” the ministry’s statement said. The facility is located in Klimovsk, a town south of Moscow.

The immigrants do not have the legal right to work in Russia, according to the police.

The Russian authorities have recently been conducting a major cross-country crackdown on illegally working immigrants, with thousands detained so far.
