Italian police on Sunday used new powers for preventative detention on anarchists seeking to take part in an unauthorised protest in Rome.
The police detained 91 people "deemed dangerous" at several different entrances to Rome's Acquedotti Park.
They wanted to take part in a march to commemorate two anarchists killed in an explosion in an abandoned farmhouse in the park on March 19, allegedly while trying to make a bomb.
Premier Giorgia Meloni's government passed a decree making it possible to detain potentially dangerous demonstrators before marches in the wake of violent protests against the closure of an anarchist centre in Turin at which some 100 police were hurt, including one who suffered fractures after being hit with a hammer, at the end of January.
"The security decree works," Meloni said on Sunday, "It does not limit freedom, but it does ensure that demonstrations are peaceful".
