One of the nastiest types of fraud is being ripped off by someone you know well and who you trusted.
It is often called affinity fraud. That is when a scammer targets a group of people, using personal contacts to con them. It could be a church group, a sports team or as community of retirees.
The fraudster joins the circle of people, gains their trust and then offers some investment that is said to be too good to miss.
One of the most famous examples is Bernard Madoff. He targeted the Jewish community and charity organisations in New York.
