Politie, Belastingdienst, ILT, and Veilig Verkeer Nederland conducted a joint operation at Waalhaven in Rotterdam, focusing on combating underminded crime. The operation led to numerous violations being uncovered, including traffic offenses and possession of illegal substances and weapons. Apart from the primary focus on underminded signals, the operation highlighted the importance of addressing broader issues like traffic safety and gathering information for criminal investigations. The vital role of integrated collaboration in tackling underminded crime in Rotterdam's harbor, a hub for criminal activities due to its logistical significance, was emphasized. Such criminal activity poses threats to society's safety and undermines the rule of law. The call to the community to report suspicious activities to combat underminded crime was reinforced.
