Where We Work


While Arkus, Inc. is a Chicago-based private investigation agency, our detectives follow each case wherever it leads. That means that we can meet all your detection needs — whether you are seeking a Chicago private investigator, a national private investigator or even an international private investigator. In fact, with over 40 years of experience in the private eye business, our detectives have captured evidence for thousands of cases on both a national and international scale.

When our detectives trail people, confirm alibis, pose as an employee, or track down and interview witnesses, they don’t stop at the U.S. borders. They pursue information wherever it resides, even if this requires a passport or a cross-country flight. Our goal is to resolve every case by getting each client the answers he or she seeks, whether those answers are to be found in Chicagoland, across the country or around the world.
