Two parked cars were destroyed by fire overnight in Raito, a hamlet of Vietri sul Mare on the Amalfi Coast.
The vehicles were parked along a road, only a few metres apart and close to residential buildings. Residents alerted firefighters after the flames had already grown high.
Firefighters extinguished the blaze and secured the area. Both vehicles were placed under seizure for further examination.
According to the report, no people or other property were harmed.
Law-enforcement officers carried out initial checks and opened an investigation into the cause. Investigators had not ruled out either an electrical short circuit or deliberate action, and the cause remains undetermined.
