The charges, made public on Monday, include the rape of four different women, domestic abuse of a former partner, and illegally filming a number of women, including their genitals, without their knowledge or consent.
He is also charged with harassment of police and traffic violations.
Høiby’s defence lawyer Ellen Holager Andenæs has been contacted for comment.
In June, when Høiby was charged with 23 offences, including three counts of rape, by the police prosecutor before the case was sent to the state prosecutor, Høiby’s defence lawyer Petar Sekulic said “he does not plead guilty to the essentials”. Høiby “strongly denies” the rape allegations, he added.
Høiby is alleged to have raped four women between 2018 and November 2024. All the alleged assaults allegedly took place after consensual intercourse while the women were sleeping. Høiby is accused of filming all the women during the alleged rapes.
As he presented the indictment against Høiby on Monday, the state attorney Sturla Henriksbø said: “This case is very serious. Rape and violence in close relationships are very serious acts that can leave lasting traces and destroy lives.”
Høiby’s status as part of the royal family, he added, would “not mean that he is treated more leniently or strictly than if similar acts were committed by others”.
