I don't generally care if someone overstays... it is their business and problem to sort out and most are not causing trouble. But there is someone who I believe is on long term overstay, who is abusive to women and people in general. I was thinking of reporting him as a possible overstay to immigration as a way to have this person deported before he causes more problems and harm.
Is there any anonymous way to go about this? Not totally necessary but would make it easier. Do the police take this seriously or not? Or would they just be looking for a pay off and let him go either way?
Thanks in advance.
