The police have released photos of a girl seen in a child abuse video on the dark web, and they are desperately trying to find her.
Detectives fear the German-speaking child is still being abused and want members of the public who recognize her to come forward to the authorities.
The girl is aged between four and five with blonde hair and brown eyes.
It is believed the child was filmed being sexually assaulted somewhere in Germany between October last year and July 2017.
The girl has been described as having a round chin and snub nose, with her straight hair in a pony tail.
Bundeskriminalamt (BKA), the German Federal Police Office, said:
“The picture and video recordings of the sexual abuse of the child were discovered for the first time in July 2017 on a child pornography platform in the so-called dark net.
“The extensive investigation carried out so far did not lead to the identification of the suspect.
“The BKA assume that the victim is still exposed to the access of the unidentified suspect, so continued sexual abuse of the child can not be ruled out.
“The Generalstaatsanwaltschaft Frankfurt am Main (Frankfurt Attorney General) and the BKA hope to identify with the support of the public the unknown victim and the unknown suspects, as well as to be able to end ongoing sexual abuse.”
