The operation, coordinated by the Central Operations Service and conducted across 44 provinces, also resulted in 954 people being charged, according to ANSA news agency. Among those arrested were 47 minors.
Police identified 973 social media profiles promoting hatred and physical violence, including attacks against law enforcement officers and the use of firearms and knives. Two of the accounts were referred to judicial authorities for possible blocking.
Officers checked approximately 188,000 people, including more than 19,000 minors, primarily in areas known for drug dealing and nightlife.
During the operation, police seized more than 700 kilograms (1,543 pounds) of narcotics, including 41 kilograms of cocaine, 660 kilograms of cannabinoids and two kilograms of ketamine. Officers also confiscated around 1,000 oxycodone pills and quantities of ecstasy, MDMA, methamphetamine and benzodiazepines.
A total of 1,182 properties were searched, including 24 reception facilities for unaccompanied foreign minors, 117 amusement arcades, 543 commercial establishments and several public gathering places.
The raids led to the seizure of €307,000 (about $351,000) in cash, 49 firearms, ammunition, 87 bladed weapons, and 95 other weapons or potentially offensive objects.
Police also recovered suspected stolen goods, including gold necklaces and mobile phones. Authorities issued 506 administrative fines, mainly over drug use and the sale of alcoholic beverages to minors.
Italy's Council of Ministers has approved new security measures that extend preventive detention rules to minors and grant local police additional powers, L'Unione Sarda reported Tuesday.
The measures, known in Italy as the "anti-maranza" rules and aimed at tackling youth crime and street disorder, were added to the Security Bill, according to the report.
Under the measures, local police may carry out preventive detention with a prosecutor's approval.
Interior Minister Matteo Piantedosi said the "so-called preventive detention regime is extended to include minors."
He said the measure could be used during specific police operations to prevent crimes that threaten public order in crowded areas, including nightlife districts.
Authorities may intervene when there are "reasonable grounds to believe" individuals could engage in conduct endangering public safety, including cases involving the "possession of weapons or objects that in any way indicate a dangerous person," he said.
The measures follow a July 2 incident at the Colosseum in which a group of youths attacked police officers and damaged a police vehicle, the report said.
Earlier measures approved on Feb. 5 included "anti-blade" provisions imposing prison sentences of up to three years for carrying a knife with a blade of at least 8 centimeters (3.1 inches) outside the home.
