The girl involved – who claims that her ex-boyfriend posted the video on Facebook against her will – also faces charges for the production of child porn.
Swiss daily 20 Minutes reports that the video, which was entitled ‘ice tea sex tape’, was originally posted on Facebook.
It quickly clocked up around 15,000 views before it was removed in December last year.
The 11 teenagers from the cantons of Zurich and Aargau are charged with downloading and distributing the video via the mobile phone application WhatsApp.
“Some people sent the video to others, while others just saved it onto their smartphones,” said Beat Fritsche, spokesman for the Public Ministry of Minors in Zurich, according to the news site.
The teenagers, some of them under 15, are expected to be ordered to perform community service.
Although police say the video was posted on the social networking site against her will, Fritsche confirmed that the girl was “accused of producing child pornography”.
In December last year, 20 Minutes reported that the girl had been subject to continuous “cyber-bullying” as a result of the video which was still being circulated on WhatsApp.
Soon after the video was posted, it was reported that pornographic pictures featuring ice tea had spread across the internet.
However, at the time it was unclear whether they featured the same girl as the original video.
