A 13-year-old Dundee schoolgirl is at the centre of shock claims that she had sex with three older boys in exchange for a cigarette.
Police are now investigating the matter.
It is alleged the group went to a flat near school grounds to carry out the act which, according to sources, was filmed on a mobile phone and posted online.
Authorities were alerted after the disturbing episode was talked about in the playground.
Pupils at the school have already been told not to discuss the investigation on the internet after the girl’s name became one of the most popular postings on Twitter in the Tayside area.
Despite this a number of insulting references have been left on Facebook, many directed towards the girl. The social networking site has since removed this content from its pages.
Local councillor George Regan said the incident exposed the dangers of Facebook, adding, “I really worry for vulnerable kids who get into this sort of thing. What they really need is help and support.”
A spokesman for Tayside Police confirmed that their investigation is ongoing but was unable to give any additional information.
Education bosses have been made aware of the matter.
