Norwegian security officers intercepted and arrested a trespasser outside the royal palace grounds shortly after midnight on Friday after an intruder forced his way into the private estate residence of Marius Borg Høiby.
Høiby, the 29-year-old son of Queen Mette-Marit, was serving court-ordered house arrest inside his home on the royal property when the perimeter breach occurred.
The intrusion shattered a quiet night. Høiby was painting and listening to music inside his quarters when heavy kicking and banging rattled the front entryway. Unaware of the danger on the other side of the threshold, he opened the door to investigate the disturbance. An unidentified man immediately shoved forward, forcing his way into the residence.
He fought back.
Høiby pushed the intruder back toward the exterior landing, physically clearing the doorway before locking down the entrance and contacting security personnel. Emergency dispatchers scrambled officers directly to the royal perimeter, where patrol units located and detained a male suspect near the residence minutes later.
The Norwegian Police Security Service took direct custody of the suspect at the perimeter edge but declined to disclose the individual's identity or criminal intent.
We can confirm that we arrested a person near Høiby's home on Friday night. Beyond that, we have no comment.

Defence counsel Alexander Greaker confirmed the breach on Saturday, emphasizing that the physical breach within a supposedly secure royal compound left his client shaken. Greaker stressed that the security perimeter had failed at a baseline level.
"Your own home is a place where you should feel safe," Greaker stated. "It is of course very serious and very unpleasant to have visitors in your own home. It is a place where you should feel safe, and in the situation Marius is in right now, it is easy to understand that he has experienced this as very unpleasant and unsafe."

Under Norwegian house arrest regulations, an individual's residence serves as an active correctional facility. Yet Friday's breach proved that unauthorized individuals could bypass estate gates, approach the front door, and make physical contact with a convicted felon under state supervision.
Investigators are currently interrogating the arrested suspect to establish whether the confrontation was a targeted assault connected to Høiby's criminal conviction or a random trespass. Norwegian prosecutors have not yet announced formal charges against the detained suspect, with an initial custodial hearing expected in the Oslo district jurisdiction.
