BERLIN — The older son of Norwegian Crown Princess Mette-Marit will be released from custody following his arrest last week regarding allegations of rape, as reported by Norwegian broadcaster NRK on Wednesday.

However, the police in Oslo have initiated an inquiry into an additional alleged sexual offense for which no formal charges have yet been made, according to NRK. Specifics surrounding this new allegation remain undisclosed at this time.

Marius Borg Høiby, who is the son of Mette-Marit from a previous relationship and the stepson to Crown Prince Haakon, does not hold any royal title or official responsibilities. He was taken into custody in Oslo under a preliminary charge of engaging in “sexual intercourse with someone who is unconscious or otherwise unable to resist the act.” This preliminary charge allows law enforcement to detain suspects while investigations are ongoing.

While the police have not disclosed when the alleged incident took place, they noted that “the victim must have been unable to resist the act.” According to reports from Norwegian outlets, Borg Høiby has denied the accusations leveled against him.

Following the allegations, the royal palace has refrained from making any statements, according to the news agency NTB. On Wednesday, law enforcement announced they would not seek further detention of Borg Høiby because there was no indication that critical evidence would be compromised, leading NRK to report that his defense attorney, Øyvind Bratlien, expressed that the release was expected. He mentioned that Borg Høiby would most likely be released later that day.

Earlier on August 4, law enforcement responded to a disturbance in central Oslo where Borg Høiby was momentarily detained, facing preliminary charges stemming from allegations of bodily harm and criminal damage, but was subsequently released. Details regarding the incident have remained unclear, although police indicated there was a connection between the suspect and the alleged victim.

Since then, additional preliminary charges have been brought against Borg Høiby, including breaching multiple restraining orders and operating a vehicle without a valid driver’s license. In total, these cases involve allegations from four different women and one man.

The situation has garnered significant attention in Norway, a country where the royal family enjoys widespread popularity. At 27 years old, Borg Høiby resides with the royal family, which includes Crown Prince Haakon and their two children, Princess Ingrid Alexandra and Prince Sverre Magnus.

The future queen of Norway, Mette-Marit, previously made headlines in 2001 upon marrying Haakon, particularly due to her status as a single mother with a lifestyle that had attracted scrutiny and included connections to a partner with a history of drug-related offenses.
