A police investigation has been launched to establish if a University of Manchester student broke child pornography laws by publishing a research paper about how he masturbated to extreme comics featuring young boys.
A parliamentary committee also heard a representative of the university reveal that that no checks were carried out before they accepted PHD student Karl Andersson.
Mr Andersson was researching subcultural Japanese comics that depict the sexual encounters of young boys, he claims to have masturbated to the same subject matter for three months and made notes on each session.
Karl's own thesis describes the material - known as shota - as a genre of self-published erotic comics that feature 'young boy characters in a cute or, most often, sexually explicit way'.
