In 2007 Klatten was blackmailed by Helg "Russak" Sgarbi, a 44-year-old Swiss national who threatened to release materials depicting the two having an affair. Sgarbi, who was charged with similar blackmail schemes against multiple women, was arrested in January 2009 and brought to court in Germany, where he was sentenced to six years in jail. His accomplice, the Italian hotel owner Ernano Barretta who allegedly filmed Sgarbi and Klatten with hidden cameras, was also arrested and was sentenced in 2012 to seven years in prison.
