Crown Princess Mette-Marit’s son Marius Borg Hoiby breaks silence after arrest

In his statement, he admits to drug use and apologizes to his family.

According to Se og Hør, Marius spent more than 30 hours in police custody on Sunday 4 August following an “incident in an apartment” in Frogner, Oslo.

The woman was diagnosed with a concussion after being admitted to hospital.

Marius, who is the stepson of Crown Prince Haakon, has spoken out via his lawyer, Oyvind Britain, in a statement shared with Norwegian outlet NRK.

He said: “Last weekend something happened that should never have happened. I committed bodily harm and destroyed objects in an apartment in the intoxication of alcohol and cocaine after an argument.

“I have several mental disorders which mean that throughout my upbringing and adult life, I have had, and still have, challenges. I have struggled with substance abuse for a long time, something I have been in treatment for in the past. I will now resume this treatment and take it very seriously.
