The request to be placed in a class 3 institution, as well as being granted permits with overnight stays, was approved by the class 2 institution where he is currently serving his sentence. However, the answer was no from the Swedish Prison and Probation Service's headquarters.
The headquarters wrote, among other things, that such an institution does not have "the degree of supervision and control deemed necessary to maintain order and security" given the "risks that still exist".
Nor would the permit conditions for Arklöv, who has carried out 39 permits over the past three years, be changed to allow him to stay overnight outside the institution.
He appealed to the administrative court, but the appeal was dismissed.
"Against the background of the risks identified by the Swedish Prison and Probation Service in relation to Jackie Arklöv, the administrative court considers that the special conditions in the case regarding security class and permits still appear necessary for security reasons, and that they are well-balanced", the court writes.
Jackie Arklöv has repeatedly applied and been denied a conversion of his life sentence to a fixed-term sentence, most recently in the Göta Court of Appeal last year.
In the afternoon of May 28, 1999, Östgöta Enskilda Bank in Kisa, Östergötland, was robbed by Tony Olsson, Andreas Axelsson, and Jackie Arklöv.
During the pursuit of the bank robbers, the 42-year-old police officer Olle Borén and his colleague Robert Karlström, 30 years old, were shot to death at close range with their own service weapons.
In June 2000, the three men were sentenced to life imprisonment by the Göta Court of Appeal.
Arklöv long denied both the robbery and the murders, but in the summer of 2001, he admitted that it was he who fired the fatal shots.
