My dad had a conversation with a police officer at the station, about getting personal details of a person that had stolen something from us. We went through there to report the case when we were told about doing a Reverse Email search. Some guy had paid for goods using a dodgy Cheque, and after reporting the case we went through to one of the places that offered the mail service. We sent them the details of the mail that we received from the guy and within a couple hours we got an address of where the guy actually stayed. He wasn’t too impressed when we showed up at his door, asking for the money or the bed.
