More than 300 books related to the Holocaust victim, including "The Diary of a Young Girl," have been found vandalised recently at libraries across Japan's capital.
Tokyo police said the man, 36, sneaked into a library on February 5 and ripped pages from 23 Frank-related books, including at least one copy of the diary. Some of the ripped pages were found in a plastic bag at an unidentified house in Tokyo.
Police said the suspect admitted to ripping the pages out of the books, but that his motive was unclear. They didn't release the suspect's name.
