How to Report Theft
Call the police. The first thing to do is to call the police and ask them to come to the location of the crime. Remain safe, and resist the urge to attempt to apprehend the thief yourself.
Wait for the police. Once the police are on their way, wait for them. Do not disturb the scene, as the police will want to see it as you found it, and dust for prints.
Tell the police everything you know. Try to determine exactly what is missing, and provide them with a list. Also tell them anyone that may be a suspect, or any other information that you have.
Obtain a copy of the police report. The police will make a report from the information you give them. You want to have a copy of this form to submit to your insurance company if you decide to make a claim with them. You will also want to have a record of the crime.
Update the police. If you discover additional items missing, or learn new information that you did not report to the police, contact them to provide the additional information. It is essential that the police have as much information as possible, to increase the likelihood that they will apprehend the thief.
