Norwegian police have detained the 27-year-old son of Crown Princess Mette-Marit, Marius Borg Høiby, on suspicion of rape, sources confirm. The arrest comes ahead of a verdict due this week in a separate sexual assault case that has already shaken the royal family. UK diplomats are closely tracking developments, as the case threatens to stain a monarchy long praised for its modern image.
Documents obtained by this paper show that Høiby was taken into custody on Saturday night after an alleged incident in Oslo. Police have not released details, but a source close to the investigation said the allegation involves a woman known to the suspect. This follows a previous charge of sexual assault from late 2023, for which a verdict is expected within days.
The British Embassy in Oslo is monitoring the situation, according to an internal note seen by our reporters. The note expresses concern about potential diplomatic fallout if the case exposes systemic failures in handling royal privilege. Høiby, who is not in line to the throne but holds a prominent public role, has denied all allegations.
The timing could not be worse for Norway's royals. The crown princess, married to Crown Prince Haakon, has faced years of scrutiny over her son's behaviour. Høiby has a history of run-ins with the law, including a previous charge for causing bodily harm. But the current rape accusation marks a new low.
Legal experts say the pre-verdict detention suggests prosecutors believe they have strong evidence. In Norway, suspects can be held if there is a risk of flight or evidence tampering. Høiby's lawyer declined to comment. The verdict in the earlier case was originally set for Monday but has been delayed, sources say, due to the new arrest.
UK diplomats are particularly interested because of the close ties between the British and Norwegian royal families. Queen Elizabeth II and King Harald V were known to be friends. But the British government has also used Norway as a model for reforming its own monarchy. Any scandal could complicate that.
Meanwhile, the Norwegian public is divided. Some call for the crown princess to step back from duties. Others defend the family, saying Høiby should be treated like any other citizen. But the palace has been silent, issuing only a brief statement confirming the arrest and expressing hope for a fair legal process.
This is not the first time Norwegian royalty has faced criminal allegations. But it is the most serious. If convicted, Høiby could face years in prison. And the damage to the monarchy could be irreversible. One source put it bluntly: "This is a nightmare they cannot wake from."
Our reporters will continue to follow the money, the connections, and the documents. The truth has a way of surfacing, even in palaces.
