What is a Private Detective, and What do They Do?

Private detectives, often called private investigators, specialise in investigating criminal and civil cases. Primarily hired by private citizens or businesses, these special agents conduct surveillance operations, do background checks, search for missing persons and facts, analyse evidence, and provide expert testimony in court proceedings. A typical workweek for a private detective may include
  • Reviewing police reports or witness testimonies.
  • Searching for records or documents relevant to a case from government sources or other vendors.
  • Interviewing potential witnesses and suspects in person or over the phone.
  • Performing surveillance operations via wires or listening devices.
  • They also offer protective services for vulnerable individuals such as VIPs.
Ultimately the goal of a private detective is to collect accurate and reliable information that may be presented as evidence in court proceedings.

How did the Profession of Private Investigator Begin?

The profession of private detective in the UK was an accidental by-product of the Industrial Revolution. Initially, civil investigations were conducted by professional law enforcement officers. Since the law enforcement officers were easily recognisable, they could not effectively pursue studies without creating suspicion. This made it necessary to employ discrete investigators who could work quietly and unseen – often former criminals who knew how to move around without drawing attention to themselves. They also had knowledge which proved helpful in investigating matters without alerting individuals or criminal gangs. As Detective agencies eventually grew in popularity and needed more staff, people with a good understanding of the law and crime began to specialise as private detectives. Their popularity remains strong today, with increasing demand for professionalised services such as security surveillance for businesses or other organisations.
