Contact your insurance agent to discuss any guidance they may provide and if required to report the event.
Maintain a written chronology of what happened, what was lost and the steps taken to report the incident to the various agencies, banks and firms impacted. Be sure to record the date, time, contact telephone number, person spoken to, and any relevant report or reference number and instructions.
File a police report and provide the facts and circumstances surrounding the loss. Obtain a police report number with the date, time, department, location and officer’s name taking the report or involved in the subsequent investigation. Having a police report on file will often facilitate dealing with insurance companies, banks, and other establishments that may be the recipient of fraudulent activity. The police report may initiate a law enforcement investigation into the loss with the goal of identifying, arresting and prosecuting the offender and possibly recovering losses.
