I can’t recall much about the site itself, but under what part of UK law was this fellow arrested? He didn’t store any illegal material, but told others where to find it. Is this “aiding and abetting” a criminal?
Ofcourse just because you’re arrested on suspicion of something, doesn’t mean you’ll be charged.
FACT intially released a statement saying that he had been arrested for “offences relating to the facilitation of copyright infringement on the Internet”. Which would be difficult as there’s no such offence in the UK.
