Munich ? A man dubbed “the Swiss gigolo” by the German media was sentenced to six years in prison Monday for defrauding Germany’s richest woman of $9 million and attempting to blackmail her for tens of millions more.

Helg Sgarbi admitted to the Munich court that he threatened to release secretly recorded videotapes of trysts with BMW heiress Susanne Klatten, 46, unless the married woman gave him millions of dollars to keep quiet.

The 44-year-old also admitted convincing Klatten to give him $9 million by saying it was for the treatment of a girl left paraplegic after he hit her with his car.

The Munich state court found Sgarbi guilty of fraud and attempted blackmail of Klatten, who turned him in to police.
