A suspected far-right extremist believed he was in a romantic relationship with the future Queen of the Netherlands when police foiled his sinister murder plot against the crown princess and her sister.

Anne Romke van der H., 33, was under the illusion that he was going on a training mission to Poland with Princess of Orange Catharina-Amalia when he was found with two axes inside a hotel room in The Hague in February, prosecutors alleged in court Monday, according to DutchNews.

The crazed man sat quietly, leaned back with his hands folded on his lap as he made his first court appearance for charges he threatened two of the three Dutch princesses, according to the outlet and Telegraaf reporter Saskia Belleman.

Van der H. was busted after hotel workers reported a disturbance to police from one of the rooms.

“I’m going to kill them all,” he allegedly repeatedly shouted from the room’s balcony before he was arrested, prosecutors claimed.

Van der H. claimed that Catharina-Amalia, the daughter of King Willem-Alexander and Queen Maxima, told him to purchase the axes as part of a survival kit for their joint mission to Poland.

“And that is exactly what he did,” his attorneys claimed, the Telegraaf reported.

Police had recovered the axes and found the words “Sieg Heil” and “Mossad” engraved into the handles. “Alexia,” the name of Amalia’s 20-year-old sister, was also found etched into one of the axes.

A handwritten note that contained both princesses’ names and the term “bloedbad 400”, Dutch for bloodbath, was found alongside the axes, prosecutors claimed.

Van der H.’s lawyers claimed “Bloedbad 400” was the name of the training mission van der H. was going on with Amalia

Officials revealed there were additional writings in the note, but were alarmed by the apparent vile notation of the princesses’ names and “bloodbath.”

Defense lawyers claimed the handwritten note was full of “incoherent words and pictures”. They argued that the prosecutor’s office had selectively chosen to include only bloodbath, Alexia and Amalia in its report.

Van der H., who has been in custody since his arrest, was ordered to remain behind bars after a judge ruled him a flight risk and believed their was a serious risk of repetition of additional threats.

The judge based his decision partly on the fact that van der H. had previously been spotted near the royal palace gardens and had admitted to a clinic last year that “he was not afraid to stab people,” Dutch News reported.

The suspect – who is from the village of Uithuizen, 165 miles northeast of The Hague – will also undergo a psychiatric evaluation to determine if he has any personality disorders.

“Given what was found in your possession, your statements on several occasions, and the fact that you were seen at the palace garden, we consider the suspicion serious enough,” the judge said, according to Dutch newspaper Algemeen Dagblad.

Van der H. allegedly shouted “Sieg Heil” and directed a Nazi salute at a police officer during a confrontation in The Hague back in January 2025, the outlet reported.

He is facing charges of spitting at and insulting officers in different incidents across the Netherlands last year.

Amalia had been the target of serious threats to her safety in the past, serious enough for her mother, Queen Maxima, to pull her out of student housing and back into the safety of the palace during her first year attending the University of Amsterdam.

During her shortened time in college back in 2022, authorities had intercepted communications from gang members that revealed a plot to kidnap the future queen and then-Dutch Prime Minister Mark Rutte.
