The police used sniffer dogs in the investigation, which were looking for something next to the road. The police did not want to say why sniffer dogs were used and what the dogs were supposed to be looking for, due to an ongoing investigation. It did become clear that the investigation was initiated at the request of the police region Noord-Nederland from Groningen. They too could not share any information about the mysterious investigation, which involved a large police presence. “I understand that this action raises questions. However, I cannot provide any more information about this at the moment,” a police spokesperson said.
