An investigation is under way into an alleged incident where a 13-year-old school girl had sex with three older boys in exchange for a cigarette.
The alleged incident involved a pupil from Craigie High School in Dundee.
Tayside Police is investigating the claims that she attended a flat near the school with three older boys before engaging in sexual activity with them in exchange for a single cigarette.
Pupils at the school have discussed the alleged incident on social networking sites Twitter and Facebook.
It is understood that police officers are examining phone footage that was taken of the alleged encounter.
A police spokeswoman said: "We are making inquiries into an incident involving a number of young people at an address in Dundee on January 12.
"Inquiries are at an early stage and officers are in the process of interviewing those believed to have been involved. It would be wrong to comment further."
A spokesman for Dundee City Council refused to say if the three boys alleged to have been involved had been suspended.
He added: "It would not be appropriate for the council to comment while a police inquiry is ongoing."
