Oslo police announced on Friday the charges against Marius Borg Hoyby, the eldest son of a Norwegian princess. It includes months of investigation into cases that include “double digits” victims for multiple counts of crimes, including rape, sexual assault and physical harm.
Hoiby, the son of Crown Prince Mette Maritt and the son-in-law of the heir to Crown Prince Hacon, has been scrutinized since his repeated arrests in 2024 amid allegations of rape and preliminary accusations of physical harm and criminal damage.
Oslo police lawyer Andreas Kruzzewski said Hoyby was cooperative during police interrogation, which is now complete. Evidence from the case was drawn from sources such as texting, witness testimony and police searches, police attorneys said.
The charges included one case of rape involving sexual intercourse and two cases of rape without sexual intercourse, four cases of sexual assault and two cases of physical harm, Kruzzefukushi said at a press conference.
“We cannot provide further details on the number of victims in an incident beyond confirming that it is a double digit number,” he said.
Defence counsel Petal Secrek said in an email to the Associated Press that Hoyby “takes the charges very seriously, but in most cases he has not admitted any misconduct, particularly in cases relating to sexual abuse or violence.”
The Royal Palace did not immediately respond to an email request from the Associated Press seeking comment. The palace, cited by Norwegian Newswire NTB, says it will not comment while passing through “normal procedures.”
This case was the top news in Norway, where the Royals are popular.
Hoyby, 28, previously lived with a royal couple and two children, Princess Ingrid Alexandra and Prince Svere Magnus, but now lives in another house nearby.
Høiby is free to hold off any possible trial and still be entitled to a presumption of innocence until the court rules.
Once known lovingly as “Little Marius,” Hoyby grew up in the public eye, enjoying the same wealth and privileges as his royal brothers, while his biological father, Morton Borg, spent time in prison for drugs and violent crimes. Høiby acknowledges cocaine use and addiction.
The future queen of Norway made headlines in 2001 when she married Hacon.
