Emotions soared during the trial at Oslo District Court, where friends of the victim, referred to as the 'Frogner woman', shared their testimony about a tumultuous night involving Marius Borg Høiby, a prominent figure in Norwegian society and the son of Crown Princess Mette-Marit. Witnesses described the distressing scene that unfolded when they entered the victim's apartment, noting the immediate signs of violence and chaos.

The trial has its roots in an incident that occurred on August 4, 2024, when Borg Høiby was first arrested following a violent episode in the apartment of his then-partner. Initially, this case has expanded into a broader investigation that now includes over 40 suspected crimes, with the oldest allegation dating back to a purported sexual assault in 2018. This dramatic escalation of the case has significantly heightened public and media interest.

As the proceedings continue, Borg Høiby has admitted to some of the property damage and parts of the physical assault. The court has now been revisiting the grim details of the night in question, revealing accounts of physical aggression including strangulation and violence that escalated to the destruction of household items. The emotional testimonies from friends have brought a visible strain to the courtroom atmosphere, emphasizing the serious implications of the case, not just for the individuals involved but for the royal family and Norwegian society at large.
