The sister of Saudi Crown Prince Mohammed bin Salman, Princess Hassa bint Salman, will be arrested under suspicion of ordering her bodyguard to beat up a worker at her Paris apartment.

A French judge reportedly issued the arrest warrant for the princess on Thursday under the French spelling Hussat ben Salmane.

Le Point, which first reported the warrant, said it was related to an incident in 2016 when the bodyguard of Princess Hassa bint Salman, who is the sister of Crown Prince Mohammed bin Salman, was arrested on suspicion of beating up a worker in her Parisian apartment.

According to news agency Agence France-Presse, the workman was suspected of taking photographs in a private apartment of the princess on Avenue Foch, an expensive street near the Arc de Triomphe, according to the report.

Newspaper Le Parisien at the time quoted the bodyguard's lawyer as saying that he had intervened on hearing his employer cry out, and that the workman had been inside the royal's private apartment, not in the area where he was supposed to be carrying out plumbing work.

The princess left the country shortly after the incident, Le Parisien reported.

Also on Thursday, NBC News reported that several U.S. officials believe the crown prince has been hiding his mother from his father King Salman.

Bin Salman, an ally of the Trump White House, has concocted various explanations for his mother's whereabouts over the years, claims NBC.

The explanations have included her being out of the country receiving medical treatment inorder for the thirty-one year old prince to keep King Salman from discovering he is behind her continued absence, the current and former officials said. MBS is due to arrive Monday to the U.S. for high level diplomatic talks.
