Tokyo police sent papers to prosecutors Tuesday on three junior high school students in Kanagawa Prefecture for allegedly sending obscene images to the governors of Tokyo and Nagano Prefecture via e-mail.

According to investigators, the three 14-year-olds attached 14 pornographic images of women to e-mail messages sent to Tokyo Gov. Shintaro Ishihara and Nagano Gov. Yasuo Tanaka in three occasions on Feb. 3 and 7.

The three were quoted as telling police that they sent the images -- which were downloaded from the Internet -- because they were angry at not receiving a reply to e-mails sent and phone calls made to the governors' offices.

They said they wanted to talk directly with Ishihara and Tanaka, although they did not have any topic they wanted to discuss; the youths also said they did not think the prank would become such a big deal, police sources said.

The Tokyo Metropolitan Government reported the incident to police in February. Investigators found through communication logs that the images were also sent to Tanaka.
