Just seen the story break on the BBC News website Small section now live http://www.bbc.co.uk/news/uk-england-london-22537941
I'm no lawyer (Rob?) ,I guess there's potential for them to make more money out of this than they would have done under normal circumstances. I'm guessing rape would come under any "Gross Misconduct" clause in a contract, so they could fire him and seek compensation, in the same way Chelsea did against Mutu when he tested positive for Cocaine. Under that I think QPR would avoid paying any more wages, and could seek compensation for an anticipated transfer fee. As Remy was on very high wages, the chances of a club coming in for him probably weren't great, especially at a decent transfer fee, so there's a chance they'd make more money this way than they would have done.
Yes, there is a possibility that if he is (a) charged (we don't know if he is accused, merely that he is being questioned) and (b) convicted, depending on the sentence, QPR could be entitled to damages for any breach of contract. I'm not really familiar with this part of employment, but I would have thought being convicted alone would not be gross misconduct under his contract - Mutu failed a drugs test which would have been directly related to his employment, whereas this is not. It may still be a breach of contract, though. Even if they did, it may well be impossible to get the money back (if Remy doesn't have much) and it would be very time consuming (Chelsea still haven't got money from Mutu...) I'm afraid I can't be more definitive!
