What Are Private Investigation Services?
Private investigations dig into specific problems when you need clear facts. Ann Arbor businesses and residents hire DK Security’s licensed investigators because we have no personal stake in the outcome. We act as neutral observers, which means no bias or drama. Whether someone’s stealing from your business, filing fake claims, or behaving inappropriately at work, we collect solid evidence so you can make smart decisions.
Your time matters—don’t waste it wondering. Whether you’re dealing with possible fraud, workplace issues, or personal legal matters, our investigators work behind the scenes to save you time and worry.
Our Ann Arbor Private Investigators Office
DK Security expanded eastward from West Michigan in 2014 to service large government security contracts in metro Detroit, including the seat of the governor at Cadillac Place.

Whether you’re looking for a traditional security guard, Michigan background screening services, or any other security systems in Ann Arbor, MI, the range of offerings we provide is extensive and always backed by experience. DK is a full-service security partner that fulfills security requests of all shapes and sizes.
One Company, One Solution
Fraud Investigation Services
Fraud costs money and ruins reputations. Our team catches fraudsters through careful watching, background checks, and detailed analysis. We give you clear proof to protect yourself or your business from scams and schemes.
Workers’ Comp Investigations
Fake workers’ comp claims hurt your bottom line, but they can be hard to spot. We quietly watch and research to confirm whether claims are real to help save your Ann Arbor business from paying for injuries that never happened.
Sexual Harassment Investigations
These sensitive cases need a careful touch. We handle workplace harassment claims with respect for everyone involved and look at witness statements, security videos, and other evidence to support your HR team and lawyers.
Anonymous Threats
When someone makes threats but won't show their face, we first figure out how serious the danger is. Our investigators use digital tracking, surveillance, and other methods to find who's behind the threats and help you feel safe again.
Employee Theft & Embezzlement Investigations
When money goes missing, it often walks out with someone you trust. If you suspect stealing or embezzlement, we identify dishonest employees through watching, checking records, and sometimes going undercover. We help your Ann Arbor business recover losses and stop the bleeding.
Vandalism
We use hidden cameras, photos, and witness accounts to build a solid case against whoever is damaging your property. If vandalism keeps happening, our investigation puts a quick stop to it.
Employee Drug Use
A drug-free workplace keeps everyone safe. We learn your company rules, talk to witnesses, help with drug testing when there's good reason, and document when employees use illegal substances or break company policy.
FMLA Surveillance
If an employee is on family or medical leave, we make sure they're not taking advantage. Our team legally monitors their activities to check if their FMLA claim is legitimate or if they're gaming the system.
Racial/Ethnic Intimidation
Everyone deserves respect at work. We take claims about racial or ethnic harassment seriously as we gather evidence about workplace bullying or discrimination. Our decades of experience help us handle these sensitive issues that affect your business, culture, and most importantly, your people.
Retail Loss
Ann Arbor stores lose big money to theft every year. We help local shops fight shoplifting, employee theft, and organized crime through smart surveillance and undercover work.
Workplace Violence
We're experts at spotting and stopping workplace violence before it happens. Our team watches concerning behavior, talks to coworkers, and creates plans to defuse threats and keep everyone safe.
Undercover Investigations
Sometimes you need eyes on the inside. We place trained investigators in your Ann Arbor business to quietly observe and document wrongdoing without anyone knowing.
Child Custody Investigations
When children's futures are at stake, we help create the best outcome. Our team uses specialized watching and interviews to report on each parent's ability and lifestyle.
