Former supermodel Cindy Crawford and her entrepreneur husband Rande Gerber have been targeted in an extortion scheme. A German man was arrested Thursday after trying to extort $100,000 from the couple over a photo of their then 7-year-old daughter bound to a chair and gagged, The Associated Press has learned.

Documents filed Thursday by the FBI and U.S. attorney’s office in U.S. District Court say an acquaintance of the couple’s former nanny has threatened to sell a photo of the child. The photo was purportedly taken by the couple’s former nanny and shows the girl bound to a chair in revealing clothing..

“A criminal complaint was filed today in federal court in Los Angeles by the U.S. Attorney’s office and the FBI stating that Rande Gerber and Cindy Crawford have been the victims of an on-going extortion scheme,” Crawford’s spokeswoman Annett Wolfsaid in a statement Thursday. “This crime has been committed by Edis Kayalar, an acquaintance of a former nanny employed by the family. Mr. Kayalar threatened to sell an image taken of the couple’s then-seven-year-old daughter. There was no previous awareness by Mr. Gerber and Ms. Crawford of the existence of the photograph when they were contacted by Mr. Kayalar. The photo was taken by the former nanny as part of a purported game without the knowledge of the parents. The couple reported the extortion threat to the police and the FBI began a criminal investigation in the matter. Rande Gerber and Cindy Crawford intend to pursue any and all available legal action against anyone who aids the perpetrator in the distribution or sale of the photograph of their daughter.”

Crawford — who was a regular presence on the runway in the 1990s — married Gerber in 1998. They have two children.
