Marius Borg Høiby, 27, Mette-Marit's son from before her marriage to Crown Prince Haakon, was arrested in August 2024 after authorities alleged he "attacked" a 20-year-old woman "psychologically and physically," according to a report from Norwegian outlet Se og Hør.

Prince Haakon spoke on his stepson’s arrest last November, stating, “Marius is facing serious accusations, which the police and the judiciary will deal with. I am convinced they will do a good job.”

The eldest son of Norway's crown princess has been charged with 32 offences, including four counts of rape, a prosecutor says. The charges against Marius Borg Høiby, 28, include the abuse of a former partner and violations of restraining orders against another former partner.
