What Does a Private Investigator Do?

A private investigator works independently, gathering evidence and information as a service to their clients. A private investigator often conducts an investigation in a workplace, home, on a missing person or researching information on financial, business, or criminal activities. Although private investigators are not authorised to perform policing acts such as arresting people, or conducting searches on a warrant, they may be asked to present the findings and results of their investigations as evidence in a court of law.
