This week a father and two sons were jailed for running boiler room scam which took st£30 million off investors. The scam involves using high pressure sales techniques to persuade people to buy what are really worth less shares. Tomas Gilmot and his sons Kevin and Christopher from England were jailed for nine-years and five years respectively. They managed to squeeze cash out of 1,700 in the well-organised family-run scam. During the trial it emerged about the fraudsters had access to a list of 46,000 potential targets which had been passed among other scam artists. (Read more about the trial here).
