21 yr old has just in last 10 minutes told me that he 'performed an act' online a short while ago to what he thought was a girl but now appears to have been a hoax and the person is demanding £20 not to post the video online. He has seen a pic of the vid and his face can be seen and the other person has posted a list of his friends/family from facebook who he will post the vid to if he doesnt pay up. He is mortified needless to say. He has rang the police but anyone have any practical advice? Anyway to trace this person/their ip address etc?
