I think you should go into specifics.
This topic has been covered before. He's almost certainly still getting paid.
1) business entities in England & Wales cannot take out insurance against illegal acts by employees - give me a link to a provider if you can prove otherwise
2) he's not been formally charged (unless someone knows different?), so there are no grounds for the employer to withhold salary for illegal activity / criminal activity
3) barring any bizarre and easily-challenged bail conditions, there's no way the criminal justice system can prevent him playing football whilst a charging decision is pending.
4) if the club chooses to "suspend" him, or otherwise not pick him, in the interim then that's the club's decision, but it isn't grounds for witholding salary
5) no agent on the planet would agree a contract containing any type of clause that would create a mechanism for witholding salary in the scenario described in 4) above.
6) gross misconduct clauses in contracts of employment exist to provide a mechanism by which an employer can unilaterally terminate said contract in the face of an egregious act that fundamentally undermines the relationship of trust between the employer and the employee. Being asked to attend a Police station in order to "assist with enquiries" doesn't meet the threshold. Being arrested, then released without charge, doesn't meet the threshold. Being bailed by the custody sergeant to reappear at a later date doesn't reach the threshold. There is an argument that merely being charged does not reach the threshold either - if the person maintains their innocence, elects for trial and is subsequently acquitted, why should they be punished by their employer BEFORE the trial even takes place?
