Geir Selvik Malthe-Sørenssen

In 2010, he published a book titled Forfalskningen ("The Fabrication") in which he alleged that the police had fabricated evidence when Arne Treholt was convicted of treason and espionage in 1985. The book was written on behalf of Treholt and Malthe-Sørenssen was paid by Treholt for his work. The book led to much controversy and to a new evaluation of the Treholt case by the Criminal Cases Review Commission. In a 2011 ruling, the commission found no evidence for Malthe-Sørenssen's claims and turned down Treholt's request to reopen his criminal case for the fourth time. The commission concluded that Malthe-Sørenssen's claims were based on fraud.[9][10][11]

In 2016, Malthe-Sørenssen was revealed by the newspaper Verdens Gang to have fabricated evidence in his attempt to have Treholt's case reopened, and his alleged source was revealed to be a used car salesman convicted of murder and fraud, with no connection to the Treholt case, who was paid by Malthe-Sørenssen to impersonate an agent of the secret service.[12][13][14][15][16][17]

After his fraud in the Treholt case was exposed, it came to light that he had engaged in similar fraud in a large number of other cases. In collaboration with the used car salesman, he had fabricated materiale in an inheritance case related to well-known lawyer Mona Høiness.[18][19] He had also engaged in blackmail of a Norwegian businessman by fabricating alleged evidence, also in collaboration with used car salesman Thor Nord.[4][20]
