Carabinieri in Chiusano di San Domenico, in the province of Avellino, arrested a 20-year-old from the Avellino hinterland after a roadside traffic stop, according to reports from IrpiniaNews, Corriere dell'Irpinia, and Ottopagine.

During the check, the young man presented an electronic identity card valid for travel abroad. Officers found the document visibly altered: its integrated microchip had been mechanically removed. A subsequent search of the vehicle found two large knives, including one folding knife.

Both the altered document and the knives were seized. The reported allegations concern possession or manufacture of false identification documents and unjustified carrying of instruments capable of causing harm.

On instructions from the Avellino Prosecutor's Office, the arrested person was taken to his home and placed under house arrest.

How officers reportedly spotted the alteration

The local reports describe practical warning signs for this type of alteration. An electronic identity card that has had its chip removed may show visible changes around the circuit area, including grooves or cuts.

According to the reports, such alterations may be detectable by holding the card up to the light or by touch, feeling for unevenness where the microchip should sit flush with the card surface.

The reports also carry a caution that removed chips could potentially be reused for cloned cards or identity fraud. That broader warning was presented by the local coverage and was not independently verified in the reporting reviewed here.

Arrest is not a final conviction

The available reports describe an arrest and a precautionary measure, not a final judgment. House arrest in this phase means the suspect was placed at home under judicial authority while the case remains under the direction of the Avellino Prosecutor's Office.

The reports do not give the suspect's name, and the exact date and time of the stop were not stated in the articles reviewed. No separately acquired official Carabinieri press release for this specific incident was found; the account is attributed by the three outlets to the Carabinieri operation and prosecutorial instructions.
