A private investigator (often abbreviated to PI and informally called a private eye), a private detective, or inquiry agent is a person who can be hired by individuals or groups to undertake investigatory law services. Private investigators often work for attorneys in civil and criminal cases. Private investigators, also called private detectives, track down and analyze information for their clients or employers. They may be called upon to assist in legal, financial and personal matters. Many private investigators have professional backgrounds in law enforcement, federal intelligence or the military.
