Marius Borg Hoiby has been under investigation since his arrest in August 2024 on suspicion of assaulting a girlfriend.

The son of Norway's crown princess has been charged with rape, domestic violence, assault and other crimes following a year-long police investigation, a prosecutor said on Monday.

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.
