Fifteen-year-old Anna Gjerdingen Jensen, head of the student council at the Ajer secondary school, raised the alarm after a number of girls began being bullied and vilified by their peers, newspaper Hamar Arbeiderblad reports.
“Here and now, I could get pictures of more than ten girls just by sending a few text messages,” Jensen told the newspaper.
Already, many of the girls are being subjected to derogatory comments after the pictures began appearing on social media websites.
“What I’m most concerned about is these girls’ futures. It can’t be especially good to apply for a job and be Googled by an employer who finds naked pictures on the web,” said Jensen.
As many of 30 girls in the town of some 30,000 inhabitants are believed to have sent pictures of themselves in various stages of undress to unscrupulous boys who have forwarded the pictures to friends or uploaded them to the internet after receiving them on their phones.
The origins of the trend are uncertain, and so far it appears to be restricted to girls in the ninth grade, who are generally 14 years old.
Police and healthcare workers have struggled to get to grips with the problem since Jensen alerted school authorities just before Christmas.
Parents of pupils at the Ajer school are to be called to an information meeting later in February. The meeting will also be attended by law enforcement and healthcare officials. Similar gatherings are set to take place at other schools in the town.
"We're going to run a programme at all lower secondary schools in the area, with a focus on netiquette and targeting concerns over girls sending pictures of themselves," police spokesman Knut Erik Amundsen told newspaper Dagbladet.
