Observations by our detectives in Dortmund

When crowds come to Dortmund, the Westfalenhalle could be fully booked. International stars regularly attract thousands of fans, and the diverse cultural offerings of the Ruhr metropolis also draw many visitors. Top-class performers in the Dortmund Concert Hall, modern and classical productions in the theatre, numerous interesting museums, and the transformation of former industrial areas into art and creative centres such as Dortmunder U – culture enthusiasts are fully catered for in Dortmund. For our detectives, this primarily means assignments on suspected infidelity in marriage or civil partnerships, as attendance at a concert or other cultural event rarely occurs alone. Many people fear a “date” between their partner and someone else, which is why they hire our Dortmund private detectives for event-related surveillance.

Other occasions for our personal observations include conferences and congresses, as well as Dortmund’s role as a shopping city. Especially during the pre-Christmas period, people from all over Germany and neighbouring countries flock to the city to supposedly shop at bargains or admire the world’s largest Christmas tree. Not everyone is honest with their spouse or partner about their intentions – the detectives of Kurtz Investigations Dortmund are happy to verify these claims through surveillance: kontakt@kurtz-detektei-dortmund.de.

When fascination for the club goes too far: investigations in custody and maintenance matters

World-class football also attracts large numbers of people to Dortmund – particularly since the phenomenal development of Borussia Dortmund (BVB) from the early 1990s, which was not stopped even by the club’s financial crisis from 2004. This city does not just live: it trembles – every weekend that Borussia Dortmund has a home game! Thousands “pilgrimage” to their “temple” – the Westfalenstadion. To this day, the Signal Iduna Park is still called this by fans, since its opening in 1974. Whether it is against the bottom team, a seemingly unbeatable Bayern, or in the Revierderby against arch-rivals Schalke 04 – the stadium is almost always sold out and holds the European attendance record with an average of over 80,000 spectators per match. More than 50,000 season ticket holders speak a clear language. And who has not heard of it: the “Yellow Wall” – the south stand of the stadium – with its nearly 25,000 vociferous fans on Europe’s largest standing terrace.

At times, however, this enthusiasm for BVB takes unacceptable dimensions. When boundaries are crossed to the detriment of others, the interests of these individuals are affected unlawfully. Specifically, this refers to inadequate care in child supervision, for example when friends attend the game and a group of men indulge excessively, while the son or daughter not only receives no attention but is also exposed to negative influences from the typically rough behaviour of the men. Another example is maintenance. Sometimes fan enthusiasm goes so far that the last money is spent on merchandise or tickets rather than fulfilling maintenance obligations (this behaviour can, of course, be transferred to other areas of excessive fandom). At this point, our Dortmund private detectives show no tolerance either but assist you as the affected party in providing legally admissible evidence of offences to your detriment: +49 231 8401 0065.
