Crown Princess Mette-Marit’s Son Facing Serious Allegations, Police Confirm
Marius Borg Høiby, son of Norway’s Crown Princess, is under investigation for multiple serious crimes, including rape.
On Friday, the Oslo Police District revealed that the 28-year-old, who lacks a royal title and does not engage in official duties, was initially detained in August 2024. His lawyer, Petar Sekulic, emphasized that Høiby is taking the allegations seriously but maintains his innocence regarding many of the accusations, particularly those involving sexual violence.
As part of the investigation, authorities conducted extensive witness interviews, searches, and a meticulous review of digital evidence. The police revealed that Høiby has been cooperative, answering questions in multiple sessions throughout the autumn and spring of 2025. Among the offenses being considered are several counts of sexual misconduct, abuse in a close relationship, and bodily harm.
While some cases of sexual offenses have been dismissed due to the statute of limitations and lack of concrete evidence, the police confirmed that the total number of victims involved is in double digits. The Royal House of Norway has stated that they will not provide additional comments as the case advances through the legal system.
