Urk mayor Bart Jaspers Faijer said the municipality is taking measures ahead of Saturday's Sinterklaas arrival because of concerns about unrest and illegal fireworks. People who are unrecognisable because of black face paint and behave suspiciously may be required to identify themselves, while hospitality businesses will not admit visitors wearing face paint. The mayor has not yet authorised preventive searches, but said that option remains available.

About 20 people who were involved in misconduct in previous years have again been notified that penalty orders against them remain valid for three years. They face a €2,500 fine if they are involved in further unrest. Police are still investigating the car explosion and fire in Wilhelminapark the previous weekend.
