Norwegian police are investigating the sudden disappearance of Dutch citizen Arjen Kamphuis, a respected security expert and known associate of WikiLeaks founder Julian Assange.
Kamphuis has been missing since since Aug. 20 and was last seen when he checked out of the Scandic Havet hotel in Bodø, Norway.
Police confirmed on Sunday that an investigation involving the National Criminal Investigation Service, known as Kripos, had been opened into the disappearance by Tuesday. Kripos are Norway’s law enforcement agency specializing in technical and forensic level investigations, both finding missing persons and fighting organized crime.
“We are investigating where he has traveled, information about the hotels he visited, telecommunications, and are questioning people who may have information,” Trond Lakselvhaug, a senior police officer, explained to local press. “Contact has been made with the police in the Netherlands. At the moment there is no reason to assume that there is a crime, but we keep all possibilities open.”
Kamphuis, 47, was due to travel 435 miles south to Trondheim, Norway, a 10-hour train ride, from where he was to fly to Amsterdam two days later. Kamphuis, however, didn’t check in for his flight.
Concerns that something might be wrong were first raised on Twitter on Friday by Dutch politician and fellow privacy activist Ancilla Van De Leest.

Kamphuis is respected for his expertise among internet activists and is perhaps best known for a book he wrote called Information Security for Journalists, in which he teaches reporters how to keep information and communications secure.
Assange currently resides in London’s Ecuadorian embassy to avoid extradition to the U.S., where he is wanted over WikiLeaks’ publication of diplomatic cables in 2010.
Meanwhile, police maintain that they will avoid speculation at this stage in the search despite signs that they are beginning to take Kamphuis’ disappearance increasingly seriously.
