Did Anne Frank tell dirty jokes in her diary, how was she discovered and who betrayed her?

MYSTERIOUS hidden pages from Anne Frank’s diary have been uncovered, revealing a side to the young Jewish diarist that was previously hidden.
Anne Frank’s diary is one of the most famous artefacts from the Nazi-era and the Second World War, and was published after her death.
Who was Anne Frank?
Anne Frank was a German-born Jewish diarist and is one of the most discussed victims of the Holocaust.
She was born on June 12, 1929 in Frankfurt, Germany.
She gained fame posthumously with the publication of her diary, entitled “Diary of a Young Girl”.
The publication was originally titled “Het Achterhuis” meaning “The Secret Annexe”.
In her diary, Anne documented her life in hiding from 1942 to 1944, during the German occupation of the Netherlands in World War II.
While Anne was born in Germany, she lived most of her live in or near Amsterdam after the Nazis took control of Germany.
Born a German national, Frank lost her citizenship in 1941 and became stateless.
By May 1940, the Franks were trapped in Amsterdam by the German occupation of the Netherlands.
As persecution of the Jewish population increased in July 1942, the family went into hiding in some concealed rooms behind a bookcase in the building where Anne's father worked.
From then until the family's arrest by the Gestapo in August 1944, Anne kept a diary she had received as a birthday present, and wrote in it regularly.
Did Anne Frank tell dirty jokes in her diary?
Researchers claim to have uncovered hidden pages of Anne Frank’s diary where she wrote "dirty" jokes about sex and prostitution.
Digital editing techniques were used to decipher the writing on two pages of the diary that the youngster had covered over with brown masking paper.
They were stunned to find four risqué jokes and a candid explanation of sex, sexual development, contraception and prostitution.
Anne would have been only 13-years-old at the time of writing these passages on September 28, 1942.
One of the jokes reads: "Do you know why the German Wehrmacht girls are in the Netherlands? As mattresses for the soldiers."
The Anne Frank Museum said this was not the only time the teenage girl wrote about sex - mentioning other jokes she had heard the people in her hidden home tell, or the passages about her periods and sexuality.
How was Anne Frank discovered?
Anne Frank went into hiding in a secret annexe of her father's business on July 6, 1942 - about a month after she received a diary for her 13th birthday.
The annexe was kept hidden by a bookcase.
Anne lived there with her family and their friends, the Van Pels, and Fritz Pfeffer, a dentist and friend of the family, until their discovery two years later.
On the morning of August 4, 1944, the building was stormed by a group of German uniformed police led by SS-Oberscharführer Karl Silberbauer of the Sicherheitsdienst.
The Franks, van Pelses, and Pfeffer were taken to RSHA (Reich Main Security Office) headquarters, where they were interrogated and held overnight.
The next day they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans.
Two days later they were transported to the Westerbork transit camp.
Having been arrested in hiding, they were considered criminals and sent to the Punishment Barracks for hard labour.
Anne died on March 12, 1945, at the Bergen-Belsen concentration camp, near Hanover after being struck down with typhus.
Just weeks after the 15-year-old's death, the Bergen-Belsen camp was liberated.
