Snapchat vid of Norwegian ‘rapist’ Royal Marius Borg Hoiby ‘showing how he slaps his exes’ emerges as he’s held in jail

A SHOCKING video of Marius Borg Hoiby has emerged that appears to show the Norwegian royal acting out how he would allegedly slap his ex.

Hoiby, 27, is currently being held in jail as police continue to probe accusations of sexual assault made against him.

The Snapchat video shows the son of Norway's Crown Princess Mette-Marit playing around as his friend films Hoiby on his phone.

In the short clip, he can be seen staring down at the camera before throwing a slap towards the camera as he laughs.

Two wine glasses appear to be sat in front of him.

The video is said to have taken just a few weeks ago, report Bild.

Norwegian magazine Se og Hør have published the clip and say it comes from a private Snapchat group that has around 50 members.

Hoiby is said to be one of these people.

They also claim that the video was made in response to a question by one of the other group members who asked: "How did you break up with your last girlfriend?"

Moments before he acts out a slap, the royal can be seen shrugging his shoulders as he pulls a joking face.

The clip has left some concerned as Hoiby has already been detained on three separate occasions over accusations of assault.

He has been charged with abuse against his ex-girlfriends Julianne Snekkestad and Nora Haukland, as well as with threatening a man in the past.

One of the victim's lawyers says the video "speaks for itself", despite it not being clear what Hoiby is referring to by the slap.

Last week, a judge ruled that the 27-year-old is to be detained behind bars for as long as a week as cops investigate claims that he assaulted not one, but two women.

Each claim against the young royal involves a "sexual encounter without intercourse", a police spokesperson said.

He was also detained back in August after allegedly attacking his former girlfriend.

The early suspicions included bodily harm, criminal damage and domestic abuse, say police.

Hoiby was released shortly after before being taken in again in September for violating a restraining order after he allegedly contacted his ex.

His residence - close to where his mum and the crown prince live - has reportedly been searched by cops.

Hoiby's lawyer Øyvind Bratlien said his client denied the charges.

He said: "He cooperates well with the police, and wants to explain himself".

According to the woman's lawyer, Hege Salomon, police brought the rape charge, not the alleged victim.

She added: "She is having a hard time, and it is heavy".

Crown Princess Mette-Marit was a single mum when she met and married Crown Prince Haakon in 2001.

Hoiby, born in 1997, was raised by the heir apparent of the Norwegian throne from three years old.

He and his step-siblings -- Princess Ingrid Alexandra, 20 and Prince Sverre Magnus, 18 -- were raised together by Mette-Marit and Haakon.
