I think the HK artist you were talking about is Edison Chen. He captured lots of movie clips while he was doing the “dirty” with a number of female movie stars and hot models. I myself didn’t pay much attention to the development, however it’s a very hot topic on the mass media as well as on the HK Chats and various chat forums on the internet. I remember vaguely that the first batch of pictures were traced to a Thai server and that’s all I know. There are new pictures being uploaded to some of the chat forums too everyday, but the HK Police is talking action against those who did so. So far there were a number of people being arrested for distribution of porno materials on the Internet which is an offence under the laws of HK. Of course there was strong reaction from the local “netizens” accusing the police of violating their freedom of information on the Internet and indeed a protest march was organized a couple of days ago.
From the initial police investigation, it was learned that Edison took his Apple computer to a shop for repair a few months ago and the technician discovered lots of dirty materials on his computer and he made a copy of it and shared that with a few close friends. However, a few months later the dirty pictures started to appear on the Internet and then a couple of the artists made a report to the police through their agency or movie companies. … the rest is history.
