The eldest son of Norway’s Crown Princess Mette-Marit is to be released from custody after his arrest last week on rape allegations.

Marius Borg Høiby, the 27-year-old son of Norwegian Crown Princess Mette-Marit, has been released from custody following his arrest last week in Oslo on preliminary rape charges. Borg Høiby, who holds no royal title or official duties, is accused of engaging in sexual intercourse with someone unable to resist, according to Norwegian authorities.

Marius Borg Hoiby, 27, was arrested in Oslo late on Monday last week on a preliminary rape charge - but police are now investigating a new alleged sexual offence

The 27-year-old son of Norway’s crown princess has been accused of a second rape just days after he was arrested on suspicion of the same offense.

Marius Borg Hoiby, the stepson of Crown Prince Haakon of Norway, was arrested on Monday. His lawyer denied the accusation and said his client was cooperating with the authorities.

On Nov. 19, Crown Prince Haakon spoke about the arrest of his stepson, 27, the day prior. Crown Prince Haakon is Marius' stepfather through his marriage to Crown Princess Mette-Marit. Mette-Marit welcomed her son Marius during a relationship that preceded her 2001 marriage to Haakon, and Marius does not have a royal role within the monarchy.

Marius Borg Hoiby has no royal title or duties, but as the stepson of the heir to the throne, his arrest has cast a cloud over Norway’s popular royal family.
