Last year there was also a lot of focus on subversion, the mixing of the underworld and the upper world. The Utrecht Administrative Intervention Team (BUIT) carried out 487 checks, the highest number to date. During the checks, (hard) drugs, laughing gas, counterfeit branded clothing, stolen vehicles and illegal employees were found. In addition, 17 violations were found during the inspection of car companies requiring a permit on the Nieuw-Overvecht business park.
