The notary, Arnold Van den Bergh, may have revealed where the Frank family was hiding in Amsterdam, claims the author of a six-year investigation into the unsolved case, the results of which were published in the book "Who betrayed Anne Frank?"

of the Canadian author Rosemary Sullivan, which appears Tuesday in French with the editions HarperCollins (420 pages, 19 euros).

The evidence against Mr Van den Bergh has been backed up by modern techniques as well as an anonymous letter sent to Anne Frank's father after World War II identifying the notary as a traitor.

The Anne Frank House museum said it was "impressed" with the investigation led by retired Federal Bureau of Investigation detective Vince Pankoke, but stressed that further investigation was needed.

"Cold case"

The teenager, known worldwide since the publication of her diary written between 1942 and 1944 while she and her family were hiding in a clandestine apartment in Amsterdam, was arrested in 1944 and died the following year, at the age of 15, in the Bergen-Belsen concentration camp.

Different theories circulated as to what led to the raid which revealed the annex where the family was hiding.

In 2016, retired FBI detective Vince Pankoke was enlisted by a Dutch documentary filmmaker to lead a team tasked with solving this "cold case".

The name of Van den Bergh, who died in 1950, had so far received little attention.

The notary was a founding member of the Jewish Council, an administrative body that the Nazis used to organize deportations.

According to investigators, his family had an exemption from deportation, and this had been revoked at the time of the Franks' betrayal, but the deportation ultimately did not take place.

Disappeared from radar

The notary disappeared from radar at the end of the war, which he survived along with the rest of his family.

But the most compelling element was the seriousness with which Otto Frank treated the allegation, Dutch media reported.

Anne's father told investigators in 1964 that he received a letter shortly after the war naming Van den Bergh as the one who betrayed the Franks and several other Jewish families.

A copy made by Mr. Frank of the letter was found by investigators in the archives of a police officer.

"We don't have a smoking gun, but we have a hot gun with empty casings next to it," Pankoke was quoted as saying by Dutch public broadcaster NOS.

Ronald Leopold, executive director of the Anne Frank House, warned that questions remained about the anonymous letter and that further investigation was needed.

Questions and doubts

"You have to be very careful about writing someone down in history like the one who betrayed Anne Frank if you're not 100 or 200 percent sure about that," he told AFP. AFP.

Other experts were more critical.

“Defamatory nonsense”, even reacted virulently Bart van der Boom, professor at the University of Leiden, to public television NOS.

"They (investigators) say he wasn't hiding, so he had to buy his security another way. But they just don't know where he was," he said.

Mr Van den Bergh's granddaughter, who told the researchers about her family history, was told of their findings last weekend.

She declined to comment on the case to the NOS.
