Here is the link, and whatever I think about Mirror journalism, the source of that article can only be the police.

Yes, Teabreid, the source of a part of the contents of that article is the police unless it is a complete lie, but the part that is from the police talks about the likelihood that some partner, relative or friend knows something material and is encouraged to come forward. That could apply no matter who the culprit, couldn't it ? I'm not questioning that the police use the press to convey occcasional drops of information and to appeal for information from the public. But I am very much questioning whether they use the press to drop hints about who the culprit is.
