Barona clan: half a millennium of sentences in 36 months for the Milanese criminal group
Within three years, the criminal association operating in the Barona district of Milan has tallied convictions totalling five centuries of imprisonment at preliminary court levels. The group, led by Nazzareno Calajò together with his nephew Luca, manages illicit activities in the Lombard metropolis. According to Il Fatto Quotidiano, the clan pursues economic interests and holds territorial influence.
The charges range from criminal association to transnational narcotics trafficking, including illegal possession of firearms, extortion and physical assault. The investigation codenamed Barrios, launched in April 2023 by antimafia prosecutors Francesco De Tommasi and Gianluca Prisco, has uncovered the internal hierarchy of the organisation. Both prosecutors are forced to move with armed security following intimidation received from the clan leader.
Calajò, held in the high-security wing of Opera penitentiary, directed threats against the magistrate: he promised to blow up the prosecutor with an explosive device. In another intercepted conversation he claimed links to Cosa Nostra, stating he was proud of such association. At present the charge of mafia-type association has not been brought against him.
The organisation can count on loyal operatives ready to shoot to protect the clan's power. Francesco Bisi, known as "Franco il bello", received a twenty-year sentence for his role as right-hand man to Luca Calajò and for safeguarding the weapons cache. Another member, Mirko Cito, negotiated a sentence of eleven years.
The district recognises the authority of the Calajòs, who have built their dominance not only through brute force but also by gaining support from segments of the population. The faces of the bosses appear in rap music videos by artists, and Nazzareno celebrated the songs composed in his honour.
Retail distribution of narcotic substances was managed by Katia Adragna, nicknamed "Mamacita", who died during the investigation. Cocaine was delivered via couriers, ordered through messaging applications and paid for through bank transfers.
The group's arsenal includes semi-automatic pistols, submachine guns and explosive devices. An affiliate listed his military equipment, mentioning a Glock and a submachine gun with eight magazines of thirty-six rounds each. The Milan Prosecutor's Office continues its investigation to complete the evidence picture.
