Criminal Record Revealed for Man Suspected of Attacking Marius Borg Høiby at Skaugum

Høiby, who is currently serving pre-trial detention with an electronic ankle monitor at the royal property, was confronted in his home when the suspect banged on the door and pushed his way inside.

The incident occurred shortly before midnight on Friday, November 6. The suspect arrived at Skaugum carrying a large suitcase, wearing two different shoes, and bringing several letters whose contents remain unknown. When Høiby opened the door, the man stated that he was there to visit him, and later after being detained indicated he had traveled to Oslo to visit Høiby’s sister, Crown Princess Ingrid Alexandra.

In a video filmed from Høiby’s perspective, the man stated that he had arrived by taxi and told Høiby jeg har pratet med deg. The royal couple was reportedly at Skaugum at the time of the breach. Following the confrontation, Høiby and the man had a conversation that was filmed.

Høiby managed to shove the intruder back out of the doorway before calling emergency services. The suspect was initially detained by the Norwegian Police Security Service (PST) before being handed over to the police.

Court records reviewed by Nettavisen reveal that the suspect has accumulated numerous convictions between 2016 and 2025. In 2017, he was sentenced to 36 days in prison for threatening NAV staff and other offenses, having written on Facebook Det e fan ikje længe te æ skyt noen inne på Nav!!!!!!, an action he later explained stemmed from frustration over being hungry and without money, adding he had no intention of following through.

In a 2021 case involving Halloween ammunition possession, he confessed without reservation after distributing 23 rounds of rifle ammunition to children trick-or-treating. Additional convictions include a 2020 sentence of ten months in prison for violence, threats, and obstructing a police officer, alongside multiple breaches of restraining orders, and 2022 rulings including a sentence of 34 days in prison and 56 hours of community service for committing violence against five different people within a short timeframe.

Legal representation for the suspect remains unsettled. Attorney Oyvind Bratlien, who the man wished to have as his lawyer in the case, has not confirmed whether his most recent 2025 sentence was appealed.

Oslo police initially dismissed the intruder with a 48-hour expulsion order without filing formal charges, operating under the preliminary assumption that no criminal offense had occurred. However, investigators reversed course on Sunday, opening a formal criminal case regarding unlawful entry and bodily harm.

Prosecutor Erlend Bakke confirmed the shift in police posture. Defense attorney Alexander Greaker, representing Høiby, maintained that official intervention was entirely appropriate given the circumstances.

Greaker told Dagbladet, adding that his client is grateful for the rapid response of law enforcement. Police prosecutor Henrik Horverak Steenfeldt-Foss stated that investigators would carry out further investigative steps, including questioning the involved parties to clarify the sequence of events.

Security around the Skaugum residence has been heightened immediately following the breach, according to reports from Se og Hør. PST senior advisor Eirik Veum stated that the security agency evaluates all protective missions continuously, though specific protective protocols remain confidential.

Investigators conducted formal questioning of Høiby in his capacity as the injured party on Monday.
