Couple of things...
Perhaps he's been named locally because he lives at that address. However if no one saw him taken away could he have a friend or a relative of the same age who is staying with him that has been arrested?
I'm intrigued by the police having a presence tonight and to find out as much about Libby as possible and that you dont have to speak to them if you dont want. That strikes me as they think Libby knew this guy and maybe even had a relationship with him? I know that seems insane but what else do they want to find out about Libby if they believe they have the right guy? Surely susually this kind of request would be to find out where she would go, or who she hung out with etc when they had more of a blank sheet.
Pawel is probably not an actual butcher. There are a lot of meat factories locally so it could be one of house. However when you're saying this person is being held on abducting someone butcher makes a much better sensationalised press report.
And on Clauda Lawrence... The police are pretty sure she was taken out the back of her house by someone she knew. Locally its believed the police know who but have never been able to get enough evidence for a conviction.
