June 15 (UPI) -- Marius Borg Hoiby has been found guilty of two counts of rape and other charges and sentenced to four years in prison.

Hoiby, the son of Norway's Crown Princess Mette-Marit, has also been convicted for domestic violence, violent threats and filming people without their consent. He pleaded guilty to assault, harassment and malicious damage to property but denied four counts of rape.

While Hoiby is the eldest son of the crown princess and stepson to Norway's heir, he is not a member of the royal family.

Hoiby faced two more counts of rape but the three judges at the Oslo District Court acquitted him on those counts. However, he is ordered to pay damages to the four women who accused him of rape in the amount of nearly $61,000.
