Police and officers from the Koninklijke Marechaussee converged on the DFDS ferry port in Vlaardingen on Tuesday morning to track down on undocumented migrants attempting the journey to the United Kingdom. A team of about thirty people were accompanied by police dogs to check any truck which caused the canines distress.
Sniffer dogs will be used to check each vehicle entering the ferry. If the dog signals that something is off, that vehicle will be thoroughly searched. Authorities were also using equipment to measure levels of carbon dioxide as a way of finding the migrants.
