You do know that the employee can simply sue you.

If you're running a business you have duty of care obligations as a Director.

You seem to be completely ignorant of the seriousness of situations like this.

I'm not talking about not-reporting, i'm talking about the uselessness of reporting... you report, the police does nothing. Who are they going to sue? You did what you had to do, the police will do nothing, and suing the police for not investigating 5000 different people from all around the world... well.. good luck with that.
