Police in North Rhine-Westphalia carried out a large operation against illegal prostitution and suspected human smuggling. More than 120 officers took part in coordinated raids across several cities.
The operation targeted a network believed to be organizing prostitution using illegal workers and short-term apartments instead of licensed brothels.
Raids Across Multiple Cities
The raids took place in several locations, including:
- Düsseldorf
- Essen
- Oberhausen
- Viersen
- Hattingen
- Langenfeld
Police searched seven properties, many of them suspected “day-use apartments” used as hidden brothels. These places often look like normal apartments but are used for prostitution during the day.
Special units, including cash-detection dogs, were also involved in the operation.
Arrests and Investigation
During the raids, officers executed two arrest warrants. The suspects were taken before a judge and placed in pre-trial detention.
The investigation is being led by prosecutors in Düsseldorf. Authorities are focusing on:
- Illegal prostitution
- Smuggling of foreign nationals
- Employment of people without valid residence permits
The suspects include three Chinese women and one Chinese man between the ages of 42 and 59.

Illegal Prostitution in Apartments
According to investigators, the network used rented apartments to organize prostitution. These apartments were advertised online and used as working places for prostitutes without legal status.
The suspects are accused of:
- Providing rooms for prostitution
- Posting ads on adult websites
- Organizing the work of sex workers
During the operation, police detained three women who were staying in Germany illegally and working as prostitutes. They were handed over to local authorities.
Police also seized around 13,000 euros in cash, along with mobile phones and digital storage devices.
What This Means
This case shows how illegal prostitution can move into normal residential buildings. These hidden brothels are harder to control and are often linked to organized crime.
Even though prostitution is legal in Germany under certain rules, illegal brothels and the use of undocumented sex workers are serious crimes.

Commentary: Risks for Customers and Property Owners
Illegal prostitution is not only risky for criminals and exploited sex workers. It also creates serious risks for customers and property owners.
For customers, the situation can become very serious if police intervene. If someone is caught inside an illegal brothel, he can be:
- Detained or arrested on the spot
- Identified by authorities
- Involved in legal procedures or fines
There is also a strong personal risk. A visit to a prostitute in an illegal brothel can become known:
- At the workplace
- Within the family
- Among friends or relatives
This can cause serious damage to a person’s reputation and private life.
Property owners also face major risks. If an apartment is used for illegal prostitution, the consequences can include:
- Police investigations and possible charges
- Damage to the reputation of the property
- Conflicts with neighbors or other business owners in the building
In many cases, even being connected to illegal prostitution can harm a business or property long-term.
The key point is simple:
illegal prostitution does not only affect those running it—it creates real legal and personal risks for everyone involved.
