In Norway, a man suspected in the Høiby case is facing allegations of witness tampering, as highlighted by his attorney, Alexander Greaker. Greaker emphasized that his client has requested a police investigation into these claims, believing it will reveal no wrongdoing. He also underscored the importance of his client's testimony for the court's independent assessment in the ongoing case, prompting them to seek prioritization in the investigation process.

The police have confirmed the initiation of an inquiry into potential obstruction of the judiciary, following statements from attorney Mette Yvonne Larsen, who represents the Frogner woman involved in the case. Kjersti Lauvsnes, a police inspector, conveyed this update to VG, indicating that the investigation will be conducted by the West Oslo police district unit. This situation illustrates the complexities surrounding the handling of testimonies and the scrutiny of interactions between legal representatives and witnesses.

The case centers around the questioning of a friend of Marius Borg Høiby, who was approached by Larsen. During their conversation, she inquired whether he advised her on how to respond to police inquiries about the ongoing investigation. Such interactions raise significant concerns regarding the integrity of witness testimonies and the judicial process, thus making this investigation critical for maintaining legal standards in the case.
