The police are searching for 33-year-old Karel Haan from the province of Groningen, who went missing on Monday night.
The Groningen man has no fixed place of residents. He is originally from Oude Pekela, but in the days before his disappearance he had been staying Odoornerveen in Drenthe. He had an appointment in Hoogeveen on Monday night, but never made it that far. Haan's mother reported him missing around midnight.
