Dutch border police have stopped 497 people from illegally entering the Netherlands in spot checks on road crossings with Germany and Belgium between January and the end of October.

In total, over 115,000 people were checked at road borders trying to access the Netherlands, according to figures provided to Dutch News by the Marechaussee on Tuesday.

A further 628 people requested asylum in the Netherlands when the vehicle they were travelling in was stopped and checked, the KMar figures show.

The Netherlands is planning to step up its border controls from December 9, but without increasing the number of officers involved. How the extra checks will be implemented, minister Marjolien Faber told parliament “is still being worked out”.

The official request to deviate from the Schengen accord, submitted by the minister to the EU, states the measure is necessary “to prevent further disruption to the migration system, as that would lead to dire circumstances and pose an increased threat to public policy”.

The document, written in English, blames the shortage of housing and a “43% increase in incidents” at reception centres for the need to reintroduce border controls “as a last resort”.

The figures, which were not sourced in the application, would appear to come from the report by the government’s scientific data agency WODC which was published in June. It details a 43% rise in total incidents alongside a 28% increase in the number of residents.

Most of the incidents (over 13,000) involved verbal and physical aggression, including threats of suicide or self harm.

Germany said on Monday it had stopped 394 people attempting to enter the country illegally from the Netherlands since it introduced tougher border checks on September 16. Of them, 205 were sent back to the Netherlands.
