More than 100 copies of Anne Frank's Diary of a Young Girl have been found vandalised in libraries across the Japanese capital, according to officials.

A total of 265 copies of the diary and other related books in 31 libraries were found damaged after the first vandalised book was found in January, prompting a wider search.

A US Jewish rights group has called for a police investigation.

The Director of Shinjuku City's Chuo Library in Tokyo, Kotaro Fujimaki, explained how he thought the vandalism took place.
