Anne Frank may not have been betrayed to Nazi occupiers, but captured by chance.

A new study by the Anne Frank House museum in Amsterdam says there is no conclusive evidence that the Jewish diarist and her family were betrayed to the Netherlands' German occupiers during World War II, leading to their arrest and deportation.

Ronald Leopold, Executive Director of the Anne Frank House museum, said in a statement Friday that new research by the museum "illustrates that other scenarios should also be considered."

One possible theory is that the Aug. 4, 1944, raid that led to Anne's arrest could have been part of an investigation into illegal labor or falsified ration coupons at the canal-side house where she and other Jews hid for just over two years.
