"There was a missing news from the Dutch police this weekend, and the police in Bodø started an initial investigation, says operations manager Tommy Bech in the Nordland Police District for NTB.
News agency AFP reported Sunday night that WikiLeaks on Saturday said that Kamphuis is reported missing by friends and colleagues. Kamphuis is described as a colleague of WikiLeaks founder Julian Assange, security expert and author of a book on information security for journalists.
Must go to Trondheim
Kamphuis left the hotel where he lived in Bodø on 20 August. He would take a train to Trondheim, where he had a plane ticket two days later, WikiLeaks writes twitter.
"We are at the beginning of the first surveys, there are some traces that we control, but we currently have no theory," says Bech to NTB.
