For clarity to other posters, this is the point at which it becomes a matter of public record, Crown Court cases are open to the public and it's deemed in the public interest to be able to name defendants in a trial. Until that point, it is not in the public interest to name suspects. The reason being is that if a defendant is named during the investigation phase and plastered over the media as a murderer (in this example) it will invietably influence any potential juror's opinion of them and can get the rial thrown out, or lead to the CPS dropping the case as they know that the defending barrister will have a reasonable chance of getting it dismissed on that basis. I'm sure Matthew S will correct me, but this is why the press releases and bulletins follow the pattern of a "25year old man has been arrested in connection with X" and nothing further until "A 25year old man has been charged with X. Joe Bloggs, 25, was arrested last week...." or similar.
This is why Article 8 is so important, even in these cases. As soon as the media names you as something, true or not, it'll stick. And they won't remove web pages that have done so. If I was arrested for murder, and despite being innocent I was named in the press as a the suspect/murderer, it'd be there forever. If anyone ever googled "TipTopTaff" they'd find online news stories saying "TTT arrested for murder" forever and ever, especially as they never normally make a big thing about being released without charge.
