CAT/C/ITA/CO/4 page 9 Vulnerable groups, including the Roma 21. While noting a number of measures adopted by the State party, including the establishment of UNAR and the Registry of Associations Working against Discrimination, the Committee expresses its concern at reports of acts of violence against and discrimination of vulnerable groups, in particular the Roma, foreigners and Italians of foreign origin and the reluctance on the part of the police and authorities to provide adequate protection to the victims and to effectively investigate those crimes.
