Carabinieri from the Compagnia Napoli Centro stopped a 14-year-old student from the province of Naples in Piazza del Plebiscito while he was carrying a knuckle-duster.
According to reports from Il Mattino and Ottopagine, the teenager told officers he only wanted to take a selfie or post a story showing himself in the square. The reports do not identify the teenager, who is a minor.
He was reported to the authorities for carrying a weapon or an object capable of causing harm.
The stop took place during a wider overnight territorial-control operation in central Naples. The same operation reportedly resulted in three other denunciations connected to knives and two denunciations involving unauthorized parking attendants.
No official Carabinieri statement or judicial follow-up was reported. The available reports do not say whether the teenager had previously displayed the object online, nor whether his stated social-media motive was independently verified.
