Anne Frank may have been betrayed by Jewish notary

Book claims to have solved mystery over who gave away family's hiding place during second world war

A Jewish notary has been named by a cold case team led by a former FBI agent as the prime suspect for the betrayal of Anne Frank and her family to the Nazis.

Arnold van den Bergh, who died in 1950, has been accused on the basis of six years of research and an anonymous note received by Anne's father, Otto Frank, after his return to Amsterdam at the end of the war.
