The future Queen of the Netherlands and her younger sister were the targets of a suspected far-right extremist who hatched a sinister Nazi murder plot against the princesses before authorities foiled the attack.

A 33-year-old man will appear in court next week after he was suspected of planning to harm Princess of Orange Catharina-Amalia, 22, and Princess Alexia, 20, in February, according to the Telegraph.

Catharina-Amalia, the daughter of King Willem-Alexander and Queen Maxima, is the heir to the throne of the Netherlands, while Alexia is second in line.

The suspect was captured in The Hague, where he was carrying two axes engraved with the names “Alexia” and “Mossad,” Israel’s intelligence agency, as well as “Sieg Heil,” the propaganda chant used by Adolf Hitler and his Nazi regime, officials said.

Authorities also recovered a handwritten note that had the words “Amalia,” “Alexia,” and “bloodbath” scrawled across the sheet.

The Hague Public Prosecutor’s Office didn’t release any additional information, including the suspect’s name, because of Dutch privacy laws.

A motive behind the planned attack and the disturbing writings was not revealed.

The royal family, or the House of Orange-Nassau, is historically Protestant. The House of Orange-Nassau, better known as the Dutch Royal family are not Jewish.

A procedural hearing is scheduled for the suspect on Monday.

The revelations of the February arrest coincided with the royal family, including Amalia and Alexia, celebrating King’s Day with public appearances in the fortified city of Dokkum on April 27.

Amalia, the young heir apparent, has been the prime subject of several sinister plots, including a suspected conspiracy by gangs to kidnap her and then-Dutch Prime Minister Mark Rutte.

In 2022, authorities had intercepted communications between gang members that messaged the future queen and Rutte, who is serving as the Secretary-General of NATO.

Queen Maxima pulled Amalia out of student housing at college and brought her back to the security of the royal palace a month into her studies over concerns about her daughter’s safety.

The then-18-year-old was a month into studying politics and economics at the University of Amsterdam and was living with several other students.

Amalia returned to living with her parents because of the threats, rarely going out in public at the time.

“It has enormous consequences for her life,” Queen Maxima said at the time. “It means that she’s not living in Amsterdam and that she can’t really go outside.”

Moroccan crime syndicate, Marco Mafia, was believed to be behind the transmissions

A year before the alleged kidnapping plot was uncovered, Amalia had attempted to form a more normal life. She applied to schools and denied a $1.87 million annual allowance from the government, according to the New York Times.

“I find that uncomfortable as long as I am not doing a lot in return and other students have it much harder,” Amalia wrote to Rutte in 2021.

When Amalia was 16, she received messages from a man over Instagram threatening to kill her friend and rape her.

He was later convicted of the threats.

The 32-year-old, identified as Wouter G. had sent “violent, sexual and frightening nature,” including threats to rape the teenager, kill her friend and that he would find her on King’s Day where she had “no escape,” according to Royal Central blog.

He was sentenced to three months in jail and mandatory treatment after prosecutors had sought a 10-month jail sentence for the conviction.
