From a farming community to an industrial location | Our corporate investigators operate in Unna

Neighbouring city of Dortmund, Unna counts 59,111 inhabitants (2015), is located in the Eastern region of the Ruhr area and grew from a small city to a medium-sized one through numerous incorporations. 396,055 inhabitants (2015) live in the district of Unna, out of which many may commute to the big cities of the Ruhr area for work, but many others also work here, in Unna. Even if the district still hosts numerous agricultural holdings, it has also grown into a strong economic location for crafts, industry, and logistics in the twentieth century. The biggest employers of the district are the logistic companies DHL and DPD as well as WILO SE, Metro, and Amazon who are storing their products in bulk warehouses here.


Unfortunately, many enterprises see themselves faced with dubious intrigues executed by third parties and even employees – Unna is no exception. Theft and embezzlement, unfair alienation of clients, espionage, warehouse and cargo crime, false claims for wages, and manipulation of expenses are only a few of many recurring offences directed against companies. Depending on the circumstances, our IHK-certified corporate detectives in Unna investigate each case individually; we will identify the offender through research and surveillance and create valid evidence with the help of our investigation results. Please send us your request through our contact form, send an email to, or give us a call for a free-of-charge and non-binding consultation to hear about the specific investigation options that are offered by our detective agency.
