Tokyo - Japanese police have arrested a man for allegedly tearing pages out of books related to Anne Frank at a Tokyo library.

More than 300 books related to Frank, including “The Diary of a Young Girl,” have been found vandalized recently at libraries across Japan's capital.

Tokyo police say the man, who was arrested Friday, sneaked into a library and ripped pages from 23 of the books on Feb. 5. Some of the ripped pages were found in a plastic bag at an unidentified house in Tokyo.

Police say the suspect, who is 36 years old, admitted to ripping the pages out of the books. They say his motive is unclear.
