A spokesman for Devon and Cornwall police told the Manchester Grauniad:Link
"Information from the public has highlighted a possibility that the offenders could be children aged 10 and over, masquerading as a paedophile. The investigations are continuing and at this moment we are looking into every line of inquiry and are not ruling out any possibility. However, the language used on the social networking sites such as Bebo and MSN is at times childish. [No change there, then - Ed]
"It could be youngsters playing a sick game to try and intimidate friends they have fallen out with. This will be treated seriously and we will be contacting the families of the children involved and we will try and help them by involving social services."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
