Video & Photographic Surveillance

Looking to catch someone in the act? There's no better proof than video or photographic evidence. Whether you suspect insurance fraud, violations of non-compete agreements, or even adultery, video and photographic surveillance can help you secure the evidence you need to prove your case.


Cheating & Infidelity Investigations

Our private investigators look into a cheating spouse or partner, stealthily track that person's movements and look into his or her personal and financial records, as allowed by law. They do this over a period of time, enough to be certain that this person is cheating or not cheating.


Child Custody

The safety and well-being of your child is your No. 1 concern as a parent. Unfortunately, if you share custody of your child with another individual, you may discover your child is exposed to unsafe situations when he/she is not in your care. A carefully conducted investigation by a private investigator from Arkus, Inc. can help you uncover the evidence you need to protect your child.


Missing Persons

At Arkus, Inc., our Illinois private detectives can help you locate:
Missing children
Lost relatives
Old friends and admirers
People who owe you money
Heirs of a deceased person
Or anyone else you need to contact


Bug Sweeps

When dealing with sensitive and proprietary information, it's important to make every effort to ensure your privacy. Unfortunately, those with a motive to steal this confidential information are often clever and can hide listening devices and surveillance equipment in places where the layperson simply doesn't think to look. That's where a team of licensed private investigators steps in.

Looking for a missing person is both terrifying and frustrating. Even with so many online resources available to the general public, some people take great measures to ensure they are well hidden from the prying eyes of others and have erased their digital and physical footprints well. Regardless of their reasons for disappearing, you will probably need professional assistance to find them. Save yourself the stress of coming up empty. Hiring a professional private investigator to find someone - even the most elusive missing person - has a much greater chance of success, because they have resources that you don't.


The licensed private investigators at Arkus, Inc. have access to information that you, as a private citizen, either do not have or cannot access without frustration.

Arkus, Inc. also supports lawyers who require assistance in building - and winning - their cases.


The trail of information the computer contains is invaluable for investigators, and the ability to get at that information, also known as computer forensics, is a skill Arkus Investigators uses to advance the investigative process. The use of the computer in illegal or illicit activities has exploded. Clients come to Arkus Investigators from many different walks of life, and we handle every case with the utmost confidentiality and the highest degree of professionalism. Internal fraud in business involving financial irregularities, employees suspected of defrauding the company, or ex-employees intentionally attempting to damage or hide data has become widespread.


Due process of law means that if you wish to file a lawsuit against an individual, you need to ensure that he or she is notified properly through delivery of certain notifications, summons and other documents pertaining to court matters. A private process server in Chicago ensures that these documents are served properly and provides you with notification of service. One of the most challenging aspects of serving court documents is locating the person whom they are being served upon. Unfortunately, in a lot of cases, the last known address is not current, and this means that he or she will have to be located.


Today, many people and businesses are on the receiving end of threats to personal and corporate security, and these can lead to physical injury, identity theft, loss of property and financial losses. When your security or privacy is threatened, it may be hard to know what to do. When you need protection from privacy or safety threats to yourself, your family, your home or your business, contact the private investigators at Arkus, Inc., one of the premier personal and corporate security services agencies in Chicago and the surrounding suburbs.


It used to be that if someone was running a background investigation on another person, that person was under suspicion for illegal behavior. That assumption can no longer be made today. Whether you're hoping to get a job or even rent a room, a background investigation in Chicago is common. If you're applying for a job working with children, you can expect your name to be run under a Chicago criminal record check to ensure the safety of the children. If you're renting, your landlord wants to be certain you pay bills on time and won't trash the place.
