He attempted to embark with the pieces of stone detached from the rock on the coast of Santa Maria Navarrese and recovered in the port of Porto Torres before being transported elsewhere.

Surveillance and control activities at the Porto Torres port area led to the identification of 15 stone pieces of various sizes, transported in the trunk of a car driven by a French tourist. The discovery was made by the special security guards on duty at the port, who immediately reported the find to the State Police personnel at the Porto Torres Maritime Border and Police Station.

The man stated that he had collected the material from the coast of Santa Maria Navarrese. The officers who responded then proceeded with the investigations and fulfilled their respective obligations, seizing the stone items and handling the subsequent procedures with the judicial authorities. Once the required procedures were completed and in compliance with the judicial authorities' orders, the State Police initiated a collaboration with the Forestry and Environmental Protection Corps of the Sardinia Region, which allowed the material to be returned to its original location.

The project thus allowed the stolen stone elements to be returned to the coastline, contributing to the restoration of the original environmental conditions and confirming the importance of collaboration between institutions and entities involved in territorial surveillance and the protection of natural heritage.
