Marius Borg Høiby was found guilty of two counts of rape, domestic abuse and other offences, and sentenced to four years in prison last month

Crown Princess Mette-Marit's son has been released on house arrest in a royal residence as he continues to appeal his sentence for rape and other charges.

Marius Borg Høiby, who was arrested in August 2024, will be transferred from prison and held at a home with an electronic tag for the next four weeks, according to VG.

The outlet said that he will stay in a royal residence near Skaugum, the home of his mother and Crown Prince Haakon.

The Norwegian Royal Household has been approached for comment.

Høiby, 29, who has been in custody since February, was found guilty of two counts of rape, domestic abuse and other offences and sentenced to four years in prison last month.

The young Norwegian had been facing 40 charges during his trial.

According to NRK, the sentence is "not yet legally binding" after the convictions were appealed by Høiby, and the state prosecutor appealed the sentencing.

Upon hearing the decision to release Høiby, police attorney Oda Karterud said: "We are satisfied that the district court has concluded that the risk of recidivism is too great for it to be justifiable to release the accused and that continued detention is necessary."

Guri Varpe, the Royal Household's head of communication, told VG: "The Crown Prince and Princess want to assist him in the phase he is currently in."

Høiby became the stepson of Crown Prince Haakon when his mother married the future king in 2001.

LATEST ROYAL FAMILY

Although he has appeared with the Norwegian Royal Family on several occasions, he holds no royal titles, succession rights, or official public duties.

His mother, the Crown Princess, has battled pulmonary fibrosis since 2018.

Speaking in front of the Oslo District Court on Monday, Høiby said he finds the arrangements around visiting his mother during her illness "extremely unreasonable", according to NRK.

He said it has been "incredibly difficult" not being able to take part in supporting his mother in her recovery.

"This is a long process that is incredibly demanding. My whole family is at home and gets to be part of the rehabilitation, standing on the outside is incredibly tough."

It is understood that he is only allowed to visit his mother once a week for a 45-minute visit.

The Palace announced that Mette-Marit had been discharged from hospital earlier today after undergoing a lung transplant last month.

According to Are Holm, Head of the Department of Respiratory Medicine at Oslo University Hospital Rikshospitalet, Mette-Marit's condition is "as good as can be expected".

Meanwhile, the Crown Princess released a statement saying she is "deeply grateful" and has been "given the gift of life".
