Undermining crime

In Wassenaar we want to be able to live, work and do business safely and pleasantly. But organized crime undermines that. Criminals abuse legal structures, such as premises, businesses or permits, to carry out their illegal activities. This is called undermining.
It often happens unnoticed. On ordinary streets. Behind ordinary front doors. That is why it is important that we stay alert together. Do you see something suspicious? Report it. Because together we can spot, fight and stop undermining.
