My dad got cheated by those scammers yesterday. How to do a report to the police? And what are the important points that we have to collect and report to the police? I had reffer to this website "welleywatch.heritage-tech.net/"

But I'm still blur on this kind report. Can someone give me a direct guide?

He is totally freak out after hearing that he got scammed. And we are not rich... HELP IS NEEDED BADLY... PLZ...
