A new mobile phone gadget has raised fears it will be a perverts' dream. The £100 add-on will turn camera phones into X-ray specs which can see through clothes.
It is said to be particularly effective on dark bikinis.
Originally designed for taking pictures at night, it has quickly been exploited by voyeurs.
Made by Japanese company Yamada Denshi, it can be bought on the internet and fitted to high-end phones. Night-filters are the latest device used by Japan's obsessive voyeur community.
The cameras effectively give users night vision by picking up on heat to create outline pictures. Because bodies are hotter than clothes, the pictures produce an image of the body without the clothes.
