Italian police have arrested a gunman suspected of a carrying out a drive-by shooting spree that targeted African immigrants.
Local news outlets said the man was detained after he stepped out of his black Alfa Romeo 147 near the memorial, gave a fascist salute and shouted, "Italy for the Italians". Police photos showed him with an Italian flag draped over his shoulders as he was arrested, and a prominent neo-Nazi tattoo on his forehead as he sat in custody.
According to Macerata police, the shootings on Saturday morning were carried out in different parts of the town, including near the train station, leading to the injuries of six people, mostly African migrants.
Six people including "persons of color" were injured, 4 of them seriously, media reported.
Mayor Romano Carancini said in a Facebook post: "Stay at home until further notice".
A man has reportedly been arrested by police. As perpetrator of crime, a Nigerian immigrant, who was engaged in sale of drugs and who has denied accusations, was arrested.
Italian media speculate that this incident may have a racist motivation and be related to case of an 18-year-old girl, Pamela Mastropiero, who was killed and dismembereded last week.
