As someone has just said, player X is innocent until proven otherwise. I imagine the un-named club will have gone through everything looking at what they were legally allowed to do regarding termination or breach of contract but ultimately, until said player is charged - and given the sensitivity surrounding it, I'm not sure what else the club could have done.
There might be a legal argument - if found guilty were the club could try and claw back earnings paid over the last 12 months since the initial allegations were made and said player has been unavailable but again, given the nature of the alleged offence the focus shouldn't really be on a rich Football Club getting it's money back, but on supporting those affected by Player X's actions.
