The number of grave crimes committed by migrants in Moscow in 2013 has risen by a third, Russian Investigative Committee's Moscow Directorate chief Vadim Yakovenko told a final collegium which focused on the Directorate's work in 2013.

"The problem of crimes committed by illegal migrants has deteriorated even further this year. In all, foreign nationals and individuals without citizenship committed 11,500 crimes in the city in 2013, i.e. more than 30 daily. This is more than a third above the figure in the same period in the year before the last," Yakovenko said.

Nationals of three Central Asian countries - Uzbekistan, Tajikistan and Kyrgyzstan - have for years remained leaders by the number of crimes committed.

Moscow investigators are especially alarmed by a sharp rise in very grave crimes committed by foreign nationals. Their number has increased by nearly one half.

"Whereas in 2012 foreigners committed one in eight murders, now it is one in five. Whereas in 2012 they committed one in three rapes, in 2013 foreigners committed 43 percent of all crimes in this category," Yakovenko said.

A total of 221 criminal cases were launched into the crimes committed by migrants against children, he said.

"At the same time, it is obvious that the actual migrant crime rates are significantly higher because the statistical accounting of these crimes only starts from the number of those already solved. This fact is confirmed by the analysis of unsolved crimes, for instance, such as rape, robbery and assaults on minors," Yakovenko said.
