in the German weekly Die Zeit from March 1995, Klaus-Dieter Knapp presented his view of the assassination as a result of a conspiracy among Swedish right-wing extremist police officers.According to this report, the murderer was identified by two witnesses who happened to be at the scene and who knew the murderer from previous encounters. PKK In 1971, Olof Palme said that he blamed the fear of the masses on "anarchists and people with long hair and people with beards." Following up on this suggestion, Hans Holmér, the Stockholm police commissioner, worked with an intelligence lead passed to him (supposedly by Bertil Wedin) and arrested a number of Kurds living in Sweden. The PKK was allegedly responsible for the murder. The lead proved inconclusive however and ultimately led to Holmér's removal from the Palme murder investigation. Fifteen years later, in April 2001, a team of Swedish police officers went to interview PKK leader Abdullah Öcalan in Turkish prison. Öcalan alleged during his trial that maybe a dissident Kurdish group, led by Öcalan's ex-wife, had murdered Palme. The police team's visit proved to be unsuccessful. In 2007, renewed allegations of PKK complicity in Palme's assassination surfaced in Turkish media during the Ergenekon investigation, which was ongoing . The Turkish newspapers have several times claimed that the PKK has admitted the murder but the PKK have always denied all claims. In 1998, the PKK said that there is a strong indication that the Turkish side is trying to discredit the PKK using Olof Palme's murder. Also many Kurdish organizations believe that the initial claims were propaganda of the Turkish government. Yugoslavian connection In January 2011 the German magazine Focus cited official German interrogation records in connection with another investigation from 2008 as showing that the assassination had been carried out by an operative of the Yugoslavian security service. The Laser Man John Ausonius, "the Laser Man", also known as John Stannerman, was initially one of the suspects but it turned out that Ausonius had a solid alibi, as he was imprisoned on the night Palme was shot. The Skandia Man In 2018, journalist and investigator Thomas Pettersson published first a series of articles in the Swedish magazine Filter and later a book, Den osannolika mördaren ("The unlikely assassin"), based on a long-running investigation into Palme's murder. Pettersson's findings were also covered elsewhere in the Swedish media, for example by Expressen and Aftonbladet newspapers.
