Marius Borg Høiby, son of Norway’s Crown Princess Mette-Marit, will not appeal a court decision to keep him detained. The 29-year-old is currently held in pre-trial custody related to a violation of a restraining order. Oslo District Court extended his detention until July 13th, citing concerns he may attempt to contact the protected party if released. Høiby was initially arrested for breaching the order concerning a woman in Frogner. He had previously requested release from custody, but the court deemed continued detention necessary. The decision indicates authorities believe there is a risk of further contact and potential interference with the case.
