For high-value theft, a police report is often required by insurance.
Theft from checked luggage is a real problem at some Italian airports. The airport police ('Polizia di Frontiera Aerea') handles these reports. Your travel insurance will typically require both a PIR and a police report to process a claim for stolen items.
