In August 2015, the Danish news website Denfri.dk filed a number of Freedom of Information requests to the government in Copenhagen, seeking the disclosure of documents concerning the alleged involvement of Denmark in a plot to arrest and extradite Snowden. On Sunday, it reported that after lengthy deliberation, it had acquired new evidence that substantiated the claim.
Among the documents published by Denfri.dk are permission for the overflight and landing of the plane, which warns that it should be operated exclusively for “state purposes of [a] non-commercial nature,” and talking points for the Transport Ministry should journalists ask about the plane.
