More than 100 street cleaners have been detained in Moscow and many will be deported for violations of immigration laws.
Federal Migration Service spokeswoman Zalina Kornilova told journalists on February 7 that 33 of the 107 detained labor migrants, who are mainly from Central Asian countries, will be deported.
Seventy-four of the detained migrant workers will have the length of their legal stay in Russia shortened.
Last month, President Vladimir Putin proposed a new law to the Russian State Duma on tightening control over the registration of migrants in Moscow.
The law targets so-called rubber apartments in which Muscovites register hundreds of migrants in tiny apartments or in abandoned apartment blocks.
Tens of thousands of Central Asian laborers travel to Russia each year to find jobs, mostly in the service and construction industries.
