Five or six Romanians were arrested by police in Rome.
The rape committed last week generated new debates on security in Italy. Two young men were arrested after a series of racist incidents targeting five Albanians in a bar in Guidona, according to the online edition of La Repubblica.
In addition, four Romanians were victims of race crimes.
These incidents were connected to the protests of far-right group Forza Nuova, which took place Saturday in Guidona, investigators said.
