Now that we know the full extent of the TalkTalk hack, the whole affair has started to quieten down. Police are still pursuing the people responsible though and now, we've been told that a fifth suspect has been arrested. Officers used a search warrant on a property in Llanelli, Wales, before apprehending an 18-year-old boy on suspicion of blackmail. Unlike the other four suspects that have been arrested -- a 15-year-old from Northern Ireland, a 16-year-old from Feltham in London, a 16-year-old from Norwich and a 20-year-old man from south Staffordshire -- he hasn't been released on bail, at least not yet. At this time, he also isn't suspected of any Computer Misuse Act offences.
