The statistics from the Italian Interior Ministry also revealed that Italian women are the victims of sexual harassment and sex attacks in most cases, and not foreign women.
In contrast, foreign women have a slightly higher rate when it comes to serious sex crimes such as violent rape, Italian daily Il Giornale reported.
Figures show foreigners now account for 31,9 percent of criminal acts despite only being eight percent of the population.
In Naples this week, a 17-year-old girl was raped, allegedly by a 30-year-old migrant. She told police that the migrant had been stalking her for a while before the assault.
He forced her into his vehicle and drove her to an isolated area where he tied her wrists and raped her.
A number of similar sexual assaults made headlines in the country, including the rape of a girl in March by a mob of five migrants from Albania and Morocco, as well as the rape of a 15-year-old in Tissino by Moroccan migrants in October. In both assaults, illegal drugs were involved.
The grisly murder of 16-year-old Desirée Mariottini, who was drugged and then raped by several migrant men who had purposely given her an overdose, had also caused a national outrage. The trial of four African men accused of raping and murdering her, began earlier this week in Rome.
Also this week, a 27-year-old man in Taranto was viciously beaten by a group of migrants “for fun”.
