Munich prosecutor Anton Winkler told the newspaper that investigators had arrested a suspect.
The latest attempt had nothing to do Swiss gigolo Helg Sgarbi, who was convicted of blackmail in March and sentenced to six years in prison after talking Klatten out of €7 million. Most of the money has not yet been recovered.
The man reportedly contacted Klatten and said he had sex videos showing her in “dangerous” situations.
The suspect however, had neither sex videos nor any relationship to Klatten, Winkler said.
Sgarbi's lawyer, Egon Geis, said his client, “knew nothing up until now about this copycat artist.”
Klatten, 46, is the daughter of the late Herbert Quandt, the German industrialist who saved BMW from collapse in 1957 and built the Bavarian carmaker into a world auto power.
Sgarbi was arrested last fall after demanding hundreds of millions of euros from Klatten in order to keep their affair secret. With an Italian co-conspirator, Sgarbi filmed his encounters with the married mother-of-three.
