The son of Norway's Crown Princess Mette-Marit has been arrested by police on suspicion of assault, before he goes on trial in Oslo on Tuesday on 38 charges, including the rape of four women, BBC reported. 

Marius Borg Hoiby, 29, was remanded in custody for four weeks. Police said the latest allegations against him involved wielding a knife and violating a restraining order, and there was a risk of reoffending.

His arrest on Sunday is the fourth time he has been detained by police since August 2024, when he was accused of assaulting a woman he had been having a relationship with, according to BBC.
