The Korps landelijke politiediensten (KLPD; English: National Police Services Agency, lit.

The KLPD was independent from the regional police forces; but like them, it was subordinate to the Dutch Ministry of the Interior and had a staff of approximately 4,500.

The National Crime Squad (Dienst Nationale Recherche, DNR) has a staff of approximately 800 employees and a number of units located around the Netherlands.

The service pays particular attention to preventive measures based on intelligence gathering, investigation and the provision of advice.

Owing to its international orientation, the DNR also plays a major role in dealing with requests from other countries for legal assistance.

Its units at non-central level are based at various places in the Netherlands, generally close to the supra-regional teams.

It is responsible for cooperation with foreign criminal investigation agencies playing a major role in tackling serious cross-border crime.

It manages Edison (the image storage system for firearms and forged documents) developed by the former NRI and specializes in fingerprint identification.

Finally, IPOL is responsible for production of the weekly TV crime-watch program ‘Opsporing Verzocht’.

They check for speeding, driving while under the influence of alcohol, drugs or medicines, and failure to wear seat belts.

Finally, the Traffic Police are responsible for combating crime on the snelweg and at rest stops.

But in major cities like Amsterdam, Rotterdam, Eindhoven and Den Haag (The Hague) they can also be called upon to help out the local police.

Another of their responsibilities is to investigate all aircraft accidents, and enforce air law, for example by conducting alcohol checks on pilots.

The DLHP has approximately half of the 120 police horses in the region of Holland and has three units based in Nunspeet, Woubrugge and Boxtel.

It ensures KLPD units are available around the clock and coordinates the deployment of personnel and equipment for large-scale police operations in the Netherlands and abroad.
