Twenty-six-year-old Edis Kayalar was found guilty of attempting to extort €100,000 ($148,505) from the supermodel and her husband, Rande Gerber, over a photo of their seven-year-old daughter gagged and bound to a chair, Reuters reported.

The photo was taken by the seven-year-olds girl's former nanny as a joke during a game of cops and robbers. According to court documents, Edis came across the picture through his friendship with the nanny.

Since last summer Edis made a number of attempts to contact Crawford and her family saying that the picture would receive a lot of money if leaked to the tabloids, court documents said.

In a statement the 44-year-old supermodel and her husband said, "We want to express our gratitude to the FBI, the U.S. District Attorney's Office in Los Angeles and the German law-enforcement authorities for their coordination and efforts in this case," People magazine reported.
