The families of six children who have died in traffic accidents submitted a criminal complaint to police Monday alleging that a teacher insulted them by uploading photos of the children on a Web site without their consent.
He copied the photos of the children from the families' Web sites.
The families also submitted a complaint claiming that the teacher, a man in his 30s who teaches at an elementary school in Hamura, Tokyo, allegedly violated the antipornography law by uploading obscene photos, including a photo of a girl's corpse, onto his site.
The teacher has been on leave since Friday at his own initiative, according to the Hamura board of education.
According to the complaints, the teacher ran a Web site called "Club Kids" from January 2003 through last month, where he posted photos of children who had died in traffic accidents along with upsetting comments and captions detailing how they were killed.
The site also carried photos of dead bodies and nude people, according to the complaints.
Tadaari Katayama, 50, held a news conference to make a case for prosecution. A picture of Katayama's 8-year-old son, Shun, who died in a traffic accident in Tokyo in 1997, appeared on the Web site.
"It is already tough for the families to live on after suffering a loss, but we've been put through days of torment as we've been subjected to people's curiosity," he said.
Papers on the teacher were sent to prosecutors in September in connection with a possible copyright violation after the family of a girl who died in a car accident in Nagoya in 2002 filed a similar complaint.
