Son of Norway’s Crown Princess Faces Expanded Charges in High-Profile Trial

Oslo, Norway – Marius Borg Høiby, the son of Norway’s Crown Princess Mette-Marit, is facing a growing number of criminal charges, including allegations of rape, assault and violations of restraining orders. The case, which began in Oslo District Court in early February 2026, has garnered significant national and international attention.

Initial Arrest and Charges

Marius Borg Høiby was initially arrested in late January 2026 following a violent incident at a woman’s apartment in Oslo. He was initially charged with assault, threats with a knife, and violating a restraining order. Prosecutors have since expanded the indictment to include a total of 40 offenses, including four counts of rape.

Expanding Legal Battles

On Monday, January 19, 2026, prosecutors added six additional charges against Høiby, including one case of gross violation of the Narcotics Act, two modern cases of violating the restraining order, and three cases of reckless driving with a motorcycle. Further charges were added on Tuesday, March 3, 2026, including reckless behavior and another violation of a visiting ban. BBC News reports that Høiby has admitted to some of the charges, including reckless behavior and violating a restraining order, but denies the four counts of rape.

Details of the Arrest

According to court testimony, the arrest occurred after Høiby and the woman were driving in a Porsche 911, despite a restraining order prohibiting contact. Høiby reportedly spotted a police car and expressed concern about being apprehended, as he did not have a valid driver’s license. He allegedly attempted to persuade the woman to drive, fearing she would crash the stolen vehicle.

The situation escalated when police stopped the vehicle. Høiby claims he was initially arrested without being informed of the reason, leading to a dispute with the officers. He asserts he refused to be apprehended until informed of the charges. Eventually, another police officer arrived and explained the reason for the arrest, after which Høiby complied.

Allegations and Testimony

The trial has included testimony from alleged victims detailing physical aggression and intimate partner violence. The Guardian reports that one former partner testified that Høiby frequently grabbed her by the throat. The Frogner woman, one of six alleged victims, reportedly cried during Høiby’s statement.

Legal Representation and Context

Marius Borg Høiby is represented by lawyers Ellen Holager Andenæs and Petar Sekulic. He is not a member of the royal family, but is the son of Crown Princess Mette-Marit from a previous relationship. The trial has sparked debate about privilege, accountability, and the scrutiny faced by those connected to the royal family. IB Times notes the case is one of the most closely watched criminal trials in Norway in recent years.

Ongoing Trial and Restrictions

The trial is ongoing, with restrictions in place, including a ban on photographs of the defendant inside or outside of court. BBC News confirms this restriction. Prosecutors outlined dozens of offenses early in the proceedings, highlighting serious violent crimes and a broader pattern of alleged misconduct.
